You would likely be better off finding a three day program. Try this one out.

I suggest doing them at the beginning, Mantello, but yes, you could do that. Let us know how it goes.

Posted on: Tue, 01/17/2023 - 15:14

It’s goes well i did
Chest and biceps on Monday
Legs on Tuesday
Back on Thursday
And shoulders and triceps on Friday
What’d you think?

Posted on: Sun, 01/01/2023 - 15:20

Hello roger, is it okay to add deadlift 4 sets of 12,10,8,6 on back day and there is a problem doing 20 total sets? Thanks in advance!

M&S Team Badge
Posted on: Sat, 01/14/2023 - 18:11

Hey Mantello, yes, that would be okay. Just don't take all four sets to failure. Save failure for the last one. 20 total sets for back would be okay.

Hello, can i replace incline db curl with barbell curl, and can i do 4 sets instead of 3!?

Hi , Which sets should we work in which rpe?

M&S Team Badge
Posted on: Thu, 04/28/2022 - 21:17

Hi, Atakhan. I would say take the final set to RPE 9 or 9.5. The others could go in a range of 6-8, depending on how you're feeling.

Five weeks into this and out of all the routines I’ve worked on this site this is the one that’s given me results so quickly in both appearance and strength going to run it another 5 weeks.

I normally do a decent 12-20k trail run on Sundays, so would like to swap the leg day to either Monday or Tuesday.

What would be the best suggestion order with the switch around?

Kind Regards,

I like the structure and layout of this workout. But how do I prevent stalling?

You can only add reps and more weight for so long, usually for me its like 3-4weeks.

Do I just change exercises every 8 weeks and change up the rep scheme? Instead of 12/10/8/6 then do sets of 8-12?

Hi is there a food plan to go with this

Hi Doug
Is it fine if I sort the routine like that:
Monday: chest.calves
Tuesday: back.biceps
Thursday: shoulders.triceps
Friday: legs

Posted on: Tue, 12/19/2017 - 11:37

Hi, are you supposed to increase the weight as the rep range goes down ? Thanks.

Hi Simon,

Yes, that is correct.

Posted on: Fri, 03/03/2017 - 09:15

After doing this 4 three or four weeks is there any other Ford a plan that Doug has made or a changeup I try to follow is Sue the most I can sometimes I do ad and another thing if I'm just completely exhausted I skip one of the exercises for the day. If you do can you give us a link

What would you recommend for ab exercises on Tuesday's and Thursday's?

Posted on: Mon, 02/22/2016 - 03:55

Situps, Crunches, Leg Raises, Decline Leg Raises, Plank. Pretty much anything you feel like that train upper & lower parts of your abs. I do lower abs on tuesdays and upper abs on thursdays.
For lower you can do crunches and leg raises.
For upper I do cable crunches, bicycle crunches, overhead situps with weight, rollouts with a barbell.

what is the recovery time between a series and the other?

Posted on: Fri, 08/07/2015 - 17:36

so im in to this 2 weeks now. i did it to change things up. i work construction ind it isn't conducive to power lifting now. i like the split i think it would be awesome for a beginner.
but i think i want to lean out a little and still be good to work, so ive added some reps and active recovery sets for the previous says session. any thoughts?

Alot of the answer to your question is: "it depends". Your additional volume and "recovery sets" might actually be deleterious in the long run if you can't recover from it given the demands of your job.

Posted on: Wed, 12/17/2014 - 12:22

Hi Steve

Sorry if this is shown somewhere on the workout but in the introduction to the workout it says "make sure you follow the correct diet program"

Is there a link to the diet program somewhere?


Posted on: Mon, 11/03/2014 - 06:11

Hey Doug, been training about 7 years now and just wondering if I can throw in a set of deadlifts on back day? been doing the stronglifts 5x5 the past month, squats were going through the roof but started losing upper body size especially in my arms(and I want big ****ing arms) so thought i would give this a go plus training three days a week wasn't enough for me.

Posted on: Wed, 10/22/2014 - 20:13

The Military Press and Bench both use Triceps as a secondary.
Mon - Shoulder and Tri's -----------Thursday - Bench and Bi's.

The workout is set up to get the most muscle gains. You will get less for your effort if you change it.
The D4D split is well thought out. I do it "as is" so I get the best results for my efforts.
You definitely get more bang for your buck with this one.

Posted on: Sat, 10/24/2015 - 17:16

whats the reason

Posted on: Sat, 10/18/2014 - 20:55

Is it okay to change the order of days in the program. ex: Switch Thursday and Monday

It is only in the hopes of distribution of work so you have ample time to recover from every workout

Posted on: Sat, 10/24/2015 - 17:09

is there a reason it should not be switched ?

Posted on: Wed, 10/08/2014 - 07:55


Why do you recommend using the smith machine for the OHP here yet bash it so hard in your article here, .Does it work better with the surrounding exercises or something in this case?

Any recommended or suggested supplements to go with this workout to encourage muscle gain and fat loss ?

Posted on: Sun, 09/07/2014 - 08:16

Hi there, when do this workout should I stick to it constantly and just increase the weight as usual or change it now and then? If so when is a good time to alternate workouts in order to increase size?


Posted on: Tue, 09/02/2014 - 21:54

I am 5'6" and weigh around 188. My goal is to get lean but muscular. I am finding it a challenge to figure out if I should lose weight while weight training to eat to maintain my current weight? Any help would be greatly appreciated.

Posted on: Mon, 09/01/2014 - 21:49

How would you recommend working pushups into the routine? I'd like to do them on more than just chest day (about 200 per day, 3 days per week)

sorry about my english but my question is in every set i have to add more weight?

Posted on: Thu, 07/31/2014 - 03:17

Hi, would it be okay to do this routine Mon, Tues, Wed, Thurs and rest Fri, Sat, and Sunday?

Posted on: Sun, 05/10/2015 - 05:41

Hi! In training we got folds of outcome, progression and regression. Resting 3 days in a row is leading to regression.
