How do you progress on this split? Do I do a weight and then once I reach the top range of the reps I increase the weight? Or just every week do I increase the weight? And what should I do if I can't do the same reps on a weight as previously done?

Hi Sean, you should try to increase the weight when you reach the top range of the reps.

If you can't, stick with that weight until you can. If you are more than two reps short, go lighter.

I hope this helps!

Hey Rafail, if you have experience with them and feel you can still recover properly, then I see no issue here. If you try it, let us know how it helps. Thanks for reading M&S!

I am 4 weeks into this program. It is kicking my butt! I also do 2 mile swims, 3 days a week. Do folks have any recommendations for recovery, so that my swims don't degrade from muscle soreness?

What's good, Chris? What are you doing for recovery now? Let me know, and we will see how we can provide more help.

Hi Roger, I'm using creatine, trying to eat healthy and drinking close to a gallon of water a day. I also track my sleep with a watch. I don't really track my eating

Pay more attention to the eating. Your body needs the quality calories and macros to recover properly. Focus on more protein for sure. This may be all you need to do for now.

Hi by the way I love the workout just wondering legs and shoulders the same day is just too much can I split them or should I try something else?

Hey Mustafa, glad you enjoy the workout overall. Sure, you can split them up if you need to. I would suggest doing legs before an off day so you have more time to recover. I hope that helps!

Hi, I'm in my mid 50's and Run between 40 to 50 miles per week
with some running specific strength sessions in the week, but am looking to build more muscle this year and cut the running back to around 25 to 30 miles a week would this be a good program to follow with my weekly milage?

Hey Bdog, thanks for reading M&S!

The calories you take in are going to matter more about building muscle, but yes, this program will serve you well. If you choose to try it, please let us know how you do, and check back in if you have more questions along the way!

Great program! Following it to the tee. Training Monday, Wednesday and Friday. I would like to do 5 km runs on Tuesday, Thursday and Saturday. Will this impact the effectiveness of the program bearing in mind I'm eating 2grams of protein per day per kg of bodyweight? Thanks in advance.

Hi Lawrence, we are glad you are enjoying it. As long as the 5K's are not wearing you out, then you should be fine to include them.

Thanks for reading M&S, and please share your results when you finish the program up. Excited to read how you did!

Hello there. Has anyone followed this program religiously for 8-12 weeks? What kind of results did you get in terms of muscle size and strength?

Owen

Good workout, but sorry, it is wildly misleading to suggest each workout could be done within 45 minutes effectively. Y’all need to stop exaggerating and start timing the workouts. Based on volume, 3-1-3 timing and assuming minimum of 60-90 secs of rest, you’re looking at 60-75mins per workout.

Jed
Posted on: Mon, 03/31/2025 - 16:21

I have been doing this workout for 3 weeks and I can generally be done in 45 to 50 minutes. Monday only takes about 40 minutes. This doesn't count stretching or cool down when I bother.

Ray
Posted on: Wed, 05/29/2024 - 08:10

Could this be done on consecutive days with a long break after? For example, could I do this on Sunday, Tuesday, Wednesday? With Thursday, Friday, Saturday and Monday as rest days?

Hi, What intensity is to be used for this routine with regards to RIR? Thanks

M&S Team Badge
Roger
Posted on: Sun, 03/31/2024 - 07:50

Last set of each exercise should be to failure. So, 0 RIR.

The first sets can be done with anywhere from 1 to 3 RIR. Use those to build up to that final set.

If you choose to use the same weight for all the sets, you should train with an intensity of 1-2 RIR.

Does this will help lose weight and build muscle, if rest days i do 40 minute treadmill with thae pace of 5

M&S Team Badge

Posted on: Sun, 03/24/2024 - 16:14

I suggest keeping at least two rest days as complete rest, but I think the treadmill work could either be done either post weight training as well as on two of those rest days.

Grant
Posted on: Sat, 02/10/2024 - 10:01

I have been doing this routine for two weeks and I was wondering what sort of cardio should I include. Will the 10 minutes on the treadmill before lifting be enough, or should I so something more on off days? Also, should I exercise abs after each routine or do a certain day?

M&S Team Badge
Roger
Posted on: Fri, 02/16/2024 - 11:28

Hey Grant, if you want to lose fat, then a couple of extra sessions of cardio such as elliptical, running, or aerobics class would be beneficial. As long as you take one complete day off a week, your recovery should be fine. Abs you can do after each of the workouts. Hope this helps!

This routines in 45 mins are impossible!

Owen

Agree, I don’t think they care about accuracy or even do the workouts themselves and time them!

I’ve been doing this workout for well over 8 weeks, and I really like it and have seen significant results, but I believe it’s time to move on. Do you have any other recommended 3-day splits I could try?

Hi,
What does 2-1-2 or 3-2-3 mean?

M&S Team Badge
Roger
Posted on: Mon, 06/26/2023 - 11:10

That is the tempo of each rep. Using 2-1-2 as an example, take 2 seconds to lower the weight, 1 second to pause, and 2 seconds to lift it back up. Hope this helps.

Love this workout. Enough sets and intensity to build solid muscle. And all in 3 workouts. Most other 3day splits don't have enough sets per body part. The only thing I've added is two Ab workouts, 4 sets each on Monday and Friday. For biceps and triceps, I do 2 exercises with 4 sets each.
This weekly workout is the same intensity as a 4 day a week split, but condensed to 3. Great time saver and definitely keeps you motivated to visit the gym regularly.

Hi, Alex. Yes, you can do that.

Finally a workout that does not pair Chest/Triceps, Back/Biceps routine. Shaun's routine of Chest/Biceps and Back/Triceps makes a lot of sense, because when you "double whammy" Chest and then Triceps,or biceps after Back, I feel this routine "burns" out the smaller body parts (Triceps/Biceps)so much that its impossible to work them properly and effectively.

Joe
Posted on: Sun, 10/24/2021 - 08:35

Hi, I am not sure how should the weight variations be. When you say 4 sets of 10 reps each, does that mean that the weight is always the same or I should increase it or decrease it at every set?

M&S Team Badge
Roger
Posted on: Mon, 10/25/2021 - 19:56

Hi, Joe. You can use the same weight or increase if you feel you need a greater challenge. Beginners should use the same weight, but intermediate and advanced trainees can add weight to increase the load.

Only 60 sec. rest between sets comes to 33 minutes.. 45 mins is not possible unless machines and weights are lined up for you in advance and still i think "45 minutes" mark is a bit too ambitious.. Unrealistic.

Paul
Posted on: Sat, 09/03/2022 - 15:41

Ok, then do 60 minutes

Unfortunately I’m not able to do pull ups. I just lack the strength and my gym doesn’t have a pull up rig for assisted pull ups. Any idea for a substitute till I have the strength to do regular pull ups?

Very new to muscle building, my question is in between sets should I be adding weight for the next set or keep the weight the same through out the exercises?
