Frequency Beats Intensity

Training each muscle group twice a week, sometimes three times, produces more growth than the classic split of one annihilating session per week. The reason is simple physiology: muscle protein synthesis stays elevated for roughly forty-eight hours after a hard session, then returns to baseline. A second exposure within that window starts the cycle again.

From a fatigue standpoint, splitting volume across more sessions is also gentler on joints and connective tissue. Twelve sets of leg work distributed across two days will leave you fresher than the same volume crammed into one.

The practical version of this is an upper-lower split, a push-pull-legs run twice over six days, or any structure that touches each muscle every three or four days. Pick the layout that fits your life and run it for at least eight weeks. Switching splits every fortnight is one of the most common reasons trainees underperform.
