Gym Workout Frequency Calculator

Count how many sessions a week train each muscle group in a full-body, upper/lower, push/pull/legs or body-part split, beside ACSM's 2 to 3 days per muscle. How it works

Reference figures

  • WHO 2020 guidelines (Bull et al., British Journal of Sports Medicine): for adults, 150 to 300 minutes of moderate-intensity or 75 to 150 minutes of vigorous-intensity aerobic activity a week, or an equivalent mix, and muscle-strengthening activity at moderate or greater intensity involving all major muscle groups on 2 or more days a week.
  • ACSM position stand (Garber et al., 2011): resistance exercises for each major muscle group on 2 to 3 days a week.
  • ACSM position stand on progression in resistance training (2009): 2 to 3 days a week for novice, 3 to 4 for intermediate and 4 to 5 for advanced training.

These are published population guidelines, not a verdict on your plan: they do not say that more than 3 days a week is harmful or that fewer is wrong for you. Splits here are common templates; the tool counts sessions and does not know your exercises, sets or recovery.

If you have a medical condition, pain, or have been inactive, ask a clinician before starting a new training plan. Stop and seek medical care for chest pain, fainting or severe shortness of breath.

About the Gym Workout Frequency Calculator

Four sessions a week of an upper/lower split train each of nine muscle groups on 2 days, within the 2 to 3 days per muscle group in the ACSM 2011 position stand. The calculator counts the days per muscle group for full-body, upper/lower, push/pull/legs and body-part splits from 1 to 7 sessions, and puts each count beside that reference without judging the plan.

Core is counted on leg and lower-body days and on every full-body day. The ACSM reference is 2 to 3 days per muscle group.

Frequently asked questions

How many times a week should you train each muscle group?
The ACSM 2011 position stand says resistance exercise for each major muscle group on 2 to 3 days a week, and the WHO 2020 guidelines say muscle-strengthening for all major muscle groups on 2 or more days. ACSM's 2009 stand on progression gives 2 to 3 days a week for novice, 3 to 4 for intermediate and 4 to 5 for advanced training.
How often does push/pull/legs train each muscle?
Three sessions (push, pull, legs) train each group on 1 day a week and six sessions on 2. Four sessions give chest, shoulders and triceps 2 days but back, biceps and the legs 1.
How often does a full-body routine train each muscle?
Every session trains every group, so 3 full-body sessions train each of the nine groups on 3 days and 4 sessions on 4, more than the 2 to 3 days in the ACSM reference. Neither ACSM nor WHO says that more days are harmful.
How often does a body-part split train each muscle?
Five sessions (chest, back, legs, shoulders, arms) train each group on 1 day a week, fewer than the 2 days in the reference. A sixth session starts the cycle again with chest, so chest gets 2 days and the rest 1.
Which split trains every muscle twice a week?
Full body from 2 sessions, upper/lower from 4 and push/pull/legs from 6. Five push/pull/legs sessions still leave the legs and core on 1 day, and a body-part split never gets every group to 2 within 7 sessions: at 7 the legs, core, shoulders and arms are still on 1.

Checking a training split

Pick the split you are thinking of and the number of sessions you can fit in a week. The table shows how many of those sessions hit each muscle group, so a gap shows before you start: a 4-day push/pull/legs rotation trains chest on 2 days but back on 1, while 4 upper/lower sessions put all nine groups on 2. Sessions are taken as one a day, in the order of the split's cycle.

Counting the days

days for a muscle group = sessions among the first N days of the split's cycle that train it, where N is your sessions per week (1 to 7). The cycles are: full body; upper, lower; push, pull, legs; chest, back, legs, shoulders, arms. Core is counted on leg and lower-body days and on every full-body day.

Example: 5 sessions of upper/lower run Upper, Lower, Upper, Lower, Upper, so chest, back, shoulders, biceps and triceps get 3 days and quadriceps, hamstrings, calves and core get 2.

Each count is shown as fewer than, within or more than the 2 to 3 days per muscle group in the ACSM 2011 position stand. The WHO 2020 guidelines ask for muscle-strengthening on 2 or more days a week.
