1 Try a deload every six weeks or so. 2  Most serious coaches recommend three or four weeks on, one week off to their intermediate and advanced trainees. 3  These are people competing in strength sports and pushing serious weight, so you may not have to deload quite so often.
A deload is a period of time in which you take things easier in the gym by lifting lighter weights or reducing your training volume. Deloads typically last a week and encourage recovery before another period of harder training with heavier loading. Even if your body doesnât absolutely need to deload, itâs a good idea. It doesnât hurt you in anyway. The worst thing about deloading is that it adds length to your program. So instead of possibly hitting a new max personal record in 9 weeks, youâll get there in 12.
