2 Day Full Body Workout: Is Twice a Week Enough?

Yes, a 2 day full body workout is enough to build muscle and strength. Because you train your whole body on both days, every muscle gets worked twice a week. The American College of Sports Medicine names exactly that as the minimum in its 2026 overview: at least two strength training sessions per week for the major muscle groups.

If you only want one recommendation: start with the A/B plan below, for example on Mondays and Thursdays, and allow about an hour per session at first. If you want a ready-made plan with a few more sets, use Full Body Essentials in the app.

An A/B plan you can copy

You need machines, a cable station and dumbbells.

Use a weight that would leave you 2–3 clean reps in reserve at the end of each set, and rest for about two minutes on the big exercises.

How many sets does each muscle get?

The table counts weekly sets from exercises that train a muscle directly:

Shoulders and arms also work during pressing and pulling, and the glutes during the leg press. Those sets are not counted here.

What this means for you: With four sets per muscle per week, you are at the low end. That is enough to start with, because beginners make progress even on a few sets. More sets do bring more, but each extra set adds a little less than the one before; that is what a meta-regression of 67 training studies shows. How little it takes to make progress is covered in the article on minimum effective volume.

More sets in the same two days

If you have time for more and are well recovered by your next session, do three sets instead of two on the first four exercises. That makes 16 sets per session and six per week for legs, chest and back. With two minutes of rest per extra set, a session then takes a good ten minutes longer.

Which days work?

At first, leave at least one day off between A and B. Monday and Thursday work well: three days until B, four until the next A. The days can change from week to week, as long as B on Sunday is not followed directly by A on Monday.

If you miss a session, carry on with it next time you train. If you miss B on Thursday, B is next on Monday, followed by A. There is no need to make it up or to do two sessions in one day. If you have been away for longer, the article on returning to training after a break can help.

Only free at weekends? Saturday and Sunday work too, but they leave you less time to recover. In a small study of 30 young men, one group trained on three consecutive days for twelve weeks, the other on three non-consecutive days. Both groups got stronger, with no clear difference between them. If you regularly manage noticeably less on Sundays, move one session to a weekday.

How you get stronger

You progress with double progression: you stay at the same weight until you reach the top of the rep range in every set, which with 8–12 means twelve. Then you add the smallest available increment and start again at the bottom of the range. How that works in detail, and what to do about large weight jumps on machines, is covered in the article on double progression.

When is a third day worth it?

For muscle growth, the ACSM review found no reliable advantage in training more often, as long as the number of sets per week stays the same. A third day is worth it if you want more sets than fit into two sessions, or if you want to get stronger in a particular exercise such as the squat: there, how often you practise it matters too. In the meta-regression of 67 studies, strength depended more clearly on frequency than muscle growth did. There is more on this in the article on training frequency per muscle group.

The two-day plan in hitPR

Full Body Essentials is the ready-made two-day plan for beginners and people returning to training, with eight exercises and 23 sets per session. Compared with the plan above, it adds dedicated exercises for the arms and rear delts, and chest, back and quads get at least six sets a week instead of four. A session takes just over an hour. The plan comes in two variants: Machines, using machines and cables, and Free Weights, with the barbell squat, bench press and Romanian deadlift. Progression is already set up, and after every workout you see what has changed.

If neither variant fits the time you have or your equipment, Adapt builds you a two-day plan with Pro, based on your goal, your experience, the time per session and your equipment. If you have less time on a particular day, you can have just that session recalculated to be shorter.
