If you want to get in shape fast without a trainer, then this might be the most important invitation you read this year.

-Dr. Carl Juneau


A Personal Invitation to Get Into the Best Shape of Your Life

This is me getting my PhD in exercise statistics at the University of Montreal

H i. My name is Dr. Carl Juneau. I’m an exercise scientist with a PhD in exercise statistics. I’ve been a coach all my life and a trainer for the Canadian Forces. So far, I’ve helped about 10,000 people get in shape 1-on-1, in group classes, and online.



On this chart, On the left, you can see that in 2005, when I got on the scale for the first time, I weighed 143 lbs. In 2009, 4 years later, I had gained 18 lbs of muscle. I was proud of that! But by 2010, I was down to 140 lbs—see that big dip on the right?

That’s how I found out that training is hard

It requires time, knowledge, and motivation. And just when you think you’re doing everything right, you can still get injured, get stuck, or lose motivation, and quit. And when you quit, you lose all your gains, and you have to start all over again…
And if that’s ever happened to you, you know how tough that is. Take it from me: I know.

In 2009, suddenly, I had trouble eating. I had no energy, couldn’t train, and felt my IQ had dropped 15 points. I used to get on the scale at least once a week to track my progress. But I stopped doing that: it was becoming too painful to see I was losing all the gains I’d worked so hard to make. Have a look:

What happened is I had become intolerant to gluten. But doctors took one year to find out. So that year, I couldn’t eat, couldn’t train, and I ended up lighter than when I first started out.

“4 years of training: gone – just like that!”

This is me getting my PhD in exercise statistics at the University of Montreal

By 2011, I had learned to manage gluten. I moved to London (England) for my PhD. And I started training with Dave Beattie.

Dave was a 5-time world champion in powerlifting, and a world-record holder in the squat. And while training under him…

In 2011, I trained under Dave Beattie in London. I gained back 21 lbs in 3 months.

How I looked sick (left) and after transforming my body for a second time (right)

“I gained back 21 lbs in 3 months.”

Now granted, when you gain back muscle you’ve lost, it’s quicker. But still, in 3 months, I gained as much muscle as I had in 4 years.

What I should have done from the start (and what you should do) is to focus on a single fundamental training principle. Every good trainers knows this. My coach Dave in London knew it. In fact, it’s exactly what the American College Of Sports Medicine recommends (ACSM, 2009).

The American College Of Sports Medicine recommends you focus on progressive overload.

And that principle is progressive overload. Progressive overload just means that to get in better shape, you need to “overload” your workout…

But the way you “overload” has to be very specific: you must increase at least one of the major training variables of your workout progressively…
So that you keep on challenging your body to transform.

Just by increasing the load, or repeating each exercise more times, you make your body think :

“Oh dear! This is new, and unexpected I need to improve”

And your body will improve and adapt by building muscle and burning fat. Over time, men usually end up quite muscular, and women, more sculpted; and both get leaner.

Plus, when you improve your fitness:


Your improve your health


Your improve your looks


Your improve your energy


Your improve your strength


Your improve your muscle mass


Your improve your confidence


Your improve your mood

“You even improve your sex life!”

You improve your self. I believe in self-improvement, and I really believe getting in shape is one of the best ways you can improve. It’s helped me tremendously.

But to make it work for you, your workout needs to start at your level, and improve with you. And the best way to ensure that, is to let a personal trainer guide you, motivate you, and update your plan in real time, as you do it. But trainers are expensive…

I know: I’ve been a trainer for 18 years. Here are just some of the men and women I’ve helped :

Now their results are not typical, and if you really want to get in shape, you’ll need time, knowledge, and motivation. That’s why training is hard. And why so many people fail, especially when they try to do it alone, without a trainer.

So, in 2016, I finished my PhD, I gathered a small team, and we started building this new technology. Our vision was to give you the ability to improve almost as fast as if you had trainer, but for much cheaper.

With this technology, you apply all the latest science and the proven tricks of an experienced trainer, automatically. Under the hood, your training is built around progressive overload. Your program :


Starts at your level


Gets more challenging as you get in better shape (it adjusts to you)


Adds new exercises as you become more experienced, fitter, and stronger


Updates in real time when you work out based on your feedback


Gives you a challenge when you feel great – Gives you a break when you’re tired

The problem Getting in shape is hard

It requires…




And even when you’re doing everything right, you can still…

Get injured…

Get stuck…

Lose motivation and quit…

Plus, personal trainers are expensive…

But there’s a solution…

“The rest-pause method resulted in greater gains in localized muscular endurance and hypertrophy for the thigh musculature.”

Prestes J. J Strength Cond Res. 2017 Apr 4.

2- Autoregulation

“Autoregulatory progressive resistance exercise was more effective than the traditional linear periodization means of programming in increasing the bench press and squat over a period of 6 week.”

Mann JB. J Strength Cond Res. 2010 Jul;24(7):1718-23

3- Regional-specific hypertrophy

“For maximal hypertrophy of an entire muscle, athletes (particularly bodybuilders) are justified in incorporating various exercises that purportedly stimulate growth in a regional-specific manner.”

Antonio J. J Stength Cond Res. 2000 Feb.

4- Daily undulating periodization (DUP)

“Making program alterations on a daily basis was more effective in eliciting strength gains than doing so every 4 weeks.”

Rhea MR. J Strength Cond Res. 2002 May;16(2):250-5.

5- Loading based on rating of perceived exertion (RPE)

“Rating of perceived exertion (RPE)-based loading may provide a small 1RM strength advantage in a majority of individuals.”

3 Science-Based Strategies That Help You Build Muscle Faster

Strategy #1 — Use “Daily Undulating Periodization” And Change Reps Every Workout

In this study published in 2002, Dr. Rhea and his team found that men who trained with DUP gained strength twice as fast

One strategy that can help you build muscle faster is daily undulating periodization (DUP). When you train with DUP, you change your weight and reps every workout. By doing so, you will build muscle and strength faster. Here’s proof:


In 2002, Dr. Matt Rhea and his team over at Arizona State University published a scientific study in The Journal of Strength & Conditioning Research (Rhea et al. 2002). They wanted to compare normal training and DUP.


In their study, 20 young men were randomly assigned to normal training or DUP training (Rhea et al. 2002). Everyone trained bench press and leg press 3 days a week.


Basically, they were doing the same number of reps, but one group did the same reps for 4 weeks at a time, while the other group changed reps every training day.

That’s why this method is called daily undulating periodization (reps undulate every day). Here’s what the 2 groups actually did:

Guys in the normal training group did:


Sets of 8 during 4 weeks


Sets of 6 during 4 weeks


Sets of 4 during 4 weeks


Total: 12 weeks

Guys in the DUP group did:


Sets of 8 on Monday


Sets of 6 on Wednesday


Sets of 4 on Friday


During all 12 weeks of the study

After 12 weeks of training… Guys who did DUP had double the strength gains (sweet!)


They improved bench press 29% (vs. 14% for guys who did normal training)


They improved leg press 55% (vs. 26% for guys who did normal training)

Size and strength are related. According to Nuckols (2016), this is especially true in experienced lifters, where gains in muscle mass may explain up to 65% of the variability in strength gains. The stronger you get, the more muscular you become. So, if you get stronger faster with DUP and Dr. Muscle, chances are, you’ll build muscle faster too.

Doing an exercise inside Dr. Muscle. Dr. Muscle applies DUP automatically and tells you exactly what to do to build muscle, burn fat, and transform your body

How To Apply Daily Undulating Periodization To Your Own Training

Rhea et al. (2003) have carried out a meta-analysis to determine the best ways to build strength. They’ve found that:


If you’ve been working out for less than a year, you should train each exercise 3 times a week


If you’ve been working out for 1 year or more, you should train each exercise 2 times a week

Most good strength coaches agree with this recommendation. So, here’s a 3-day-a-week template you can follow to apply DUP to your own training and build muscle faster:

Week 1:


Monday: 12 reps


Wednesday: 6 reps


Friday: 9 reps

Week 2:


Monday: 11 reps


Wednesday: 5 reps


Friday: 8 reps

Week 3:


Monday: 10 reps


Wednesday: 4 reps


Friday: 7 reps

When you reach week 4, repeat weeks 1-3. A few remarks on this template:


You’ll always perform between 4 and 12 reps. Most bodybuilding coaches agree this is the best rep range to build muscle


You’ll perform fewer reps on Wednesday. This enhances recovery and may be the best DUP pattern (Zourdos et al. 2016)

This is the 3-day-a-week template we use for people who have been training for less than a year in our new app Dr. Muscle. You can apply it by yourself in your own training. Or you can let Dr. Muscle handle everything for you, while you focus on lifting heavy and getting jacked. I’ll tell you more about Dr. Muscle in a minute.

For people who have been training for 1 year or more, we use a similar 2-day-a-week template on an A/B split.

Strategy #2 — Finish Strong With A “Plus Set” To Find Out How Much Heavier You Should Lift To Keep Building Muscle Fast

In 2010, Dr. Bryan Mann and his team over at the University of Missouri published a scientific study in the The Journal of Strength & Conditioning Research (Mann et al. 2010).

They found that if you increase the weight you lift by a set amount each week (like most guys who work out), you may be shooting yourself in the foot.

Instead, you should determine how much weight you add to the bar by using a novel strategy they called autoregulatory progressive resistance exercise (also called “plus sets”). In their study, they had 23 collegiate football players train using two different strategies for progression:


Plus sets


Increase weights by a set amount each week (for the squat: 3 sets of 8 reps @ 70% 1RM during week 1, 4 sets of 6 reps @ 75% 1RM during week 2, 4 sets of 5 reps @ 80% 1RM during week 3, and 4 sets of 5 reps @ 85% 1RM during week 4)

After 6 weeks of training, the plus set strategy proved superior:


Bench press 1RM increased by 93.4 N (vs. -0.40 N for guys who did normal training)


Estimated squat 1RM increased by 192.7 N (vs. 37.2 N for guys who did normal training)


225-lb bench press reps to fatigue increased by 3.13 (vs. -0.9 for guys who did normal training)

Bottom line, guys who used the plus set strategy got stronger faster. They were also able to bench press 225 lbs for 3 extra reps after just 6 weeks of training (whereas guys who did normal training weren’t able to do even 1 extra rep).

Why was this strategy superior? The authors explain that it…

Allows adaptation of a particular workout by the individual athlete based on their abilities for that particular day (Mann et al. 2010).

In other words, this strategy makes sure you push yourself every workout, and helps you pick just the right weight to keep building strength and muscle fast.

How to Do a Plus Set To Build Strength (And Muscle) Faster

For a set of 6RM, Dr. Mann et al. (2010) provide the following guidelines:

Set 1

Do 10 reps at 50% of the anticipated 6RM

Set 3

Do as many repetitions as you can with 100% of your anticipated 6RM (this is your plus set)

Set 2

Do 6 repetitions at 75% of the anticipated 6RM

Set 4

Adjust based on your results from the previous set

How much weight should you add to the bar after your plus set?


If you did 5-7 reps, keep weight the same


If you did 8-12 reps, add 5-10 lbs


If you did >13 reps, add 10-15 lbs

Plus Set Guidelines Relative To Your Own Strength Level

Adding 5 lbs to the bar won’t feel the same if you squat 100 or 1,000 lbs.

So, it makes sense to follow relative guidelines when applying this strategy. I got this tip from Dr. Mike Zourdos on podcasts with Jovanovic (2015) and Iraki (2016).

A big advantage is these guidelines will apply to most exercises, even if they inherently let you lift light weights (e.g. biceps curls) or very heavy weights (e.g. leg press).

I’ve combined Dr. Mann’s and Dr. Zourdos’ guidelines to make the following guidelines for plus sets:


Set 1: do 10 reps at 50% of the anticipated 6RM


Set 2: do 6 repetitions at 75% of the anticipated 6RM


Set 3: do as many repetitions as you can with 100% of your anticipated 6RM


If you did 5-7 reps, keep weight the same


If you did 8-10 reps, add 1%


If you did 10-12 reps, add 2.5%


If you did >13 reps, add 4%


Set 4: do as many reps as you can with your new weight

Do your plus set at the end of the week (or microcycle). Start your next week (or microcycle) with the new weight you used on your 4th set. Grind that weight all week, and finish the week strong again with a plus set. Rince, repeat. Get strong and big.

Plus sets let you start every week with just the right weight to keep building strength and muscle fast:


If you can do lots of extra reps on your plus set, you’ll add more weight, and you’ll keep progressing fast.


If you can’t do extra reps on your plus set, you’ll know you need another week with the same weight. You avoid overtraining and even perhaps injuries.

Either way, plus sets help you pick just the right weight to keep building muscle fast in a safe way.

We’re adding plus sets in our new bodybuilding workout app Dr. Muscle. It will automatically prompts you to do a plus set. It will logs your results, and it will automatically adjusts your weights accordingly.

Strategy #3 — Add New Exercises As You Max Out Old Ones To Hypertrophy More Muscle Fibres

Every exercise you do targets some parts of your muscles more than others. So, when you max out an exercise, it makes sense to add a new one to your routine to hypertrophy your muscles fully.

Imagine you work out your chest. Let’s say you do:


Incline bench press (targets the clavicular head of your pectoralis major)


Decline bench press (targets the sternocostal head of your pectoralis major)


By doing 3 sets of each, you hypertrophy your chest in full—more than you would have if you had done 6 sets of incline bench only.

Exercise scientists call this regional muscle hypertrophy (Antonio 2010). Beardsley (2016) reviewed the science on regional hypertrophy and noted:

Regional hypertrophy may occur because some parts of a muscle are sufficiently activated during an exercise, while others are not. Wakahara et al. (2012; 2013) measured the regional differences in post-exercise muscle activation during a single training session, using magnetic resonance imaging (MRI) scans, as well as the regional hypertrophy following a long-term training intervention for the triceps brachii. They found that differences in regional activation in certain parts of a muscle were correlated with increases in muscular size in the same parts of the muscle.

In other words, if you want to hypertrophy your muscles in full, you should do multiple exercises that stimulate growth in different regions of your muscles.

When Should You Add New Exercises To Your Routine?

We’ve just established that should you do multiple exercises to hypertrophy your muscles in full. But if you’re just starting out, there’s no way you can perform 5 exercises for each muscle group. So what should you do? You should add new exercises to your routine as you max out old ones.

Let’s return to our example for the bench press. Imagine you start training the incline bench press. You can expect to progress fast during the first few weeks. But then, progress slows down. A typical progression for an average lifter may be:


Day 1: 45 lbs (just the bar)


After 2 weeks: 95 lbs (50 lbs increase)


After 4 weeks: 115 lbs (20 lbs increase)


After 6 weeks: 125 lbs (10 lbs increase)


After 8 weeks: 130 lbs (5 lbs increase)

From that point on, your incline press has more or less stalled. It’s almost maxed out. You’ve already gained most of your strength for that exercise. Now that you’re strong and you lift heavy, this exercise stimulates parts of your muscles hard. It has become a good driver for hypertrophy. But this hypertrophy is specific to your upper pectorals.

Instead of (almost) wasting your time training the incline bench press again and again, you would do well to train another (related) exercise to hypertrophy another region of your pectorals. The decline bench press would be perfect in this example, because it targets the bottom of your pectorals.

So, when you should add a new exercise to your routine? The answer is: when your previous exercise for that muscle group has maxed out.

Adding New Exercises In Rotation

Let’s recap. You work out your chest. You start with the incline press. At first, you train the incline press every time you train your chest, because you’re still making progress fast. Your routine looks like this:


Day 1: incline press


Day 2: incline press


Day 3: incline press

After 8 weeks, you’ve maxed out the incline press. You add in the decline press. Your routine now looks like this:


Day 1: incline press


Day 2: decline press


Day 3: incline press


Day 4: decline press

This lets you maintain (or even slightly improve) your incline press, while also bringing up your decline press. You train for another 8 weeks, and now you’ve also maxed out your decline press. You add the flat bench press to your rotation. Your routine now looks like this:


Day 1: incline press


Day 2: decline press


Day 3: flat bench press


Day 4: decline press


Day 5: incline press


Day 6: flat bench press

Once again, this routine lets you maintain your incline and decline bench press, while you bring up your flat bench press. You’re now training 3 exercises for your chest, and you hypertrophy your pectorals in full.

This is how you add in new exercises in rotation to your routine. With this strategy, you can get strong and hypertrophy all regions of your muscles. We’ve automated that process in Dr. Muscle with workout plans that progress automatically.

As soon as you’ve maxed out the exercises for your level, the app recommends you switch to more advanced workouts that include new exercises in rotation. You then train both exercises (the old and the new) in rotation, until you’ve maxed both. Following the same logic, the app then recommends you advance to the next level, and so on. With Dr. Muscle, you can hypertrophy your entire muscles, and the process is 100% automated.

Offline Access

Dr.Muscle used to require an internet connection to work. That was a problem for some users working out in gyms with bad Wi-Fi. With the offline access update, you'll only need to connect before and at the end of your workout (you can even connect before you leave the house and when you return)!

New Home Screen

On your new home screen, you'll now see stats like:
∗ How many workouts you've done
∗ How much you've lifted total
∗ Your strength (last 3 workouts)
∗ Your volume (last 3 workouts)

And more! In doing so, you can now track your volume, which is a great way to progress your training for size
