Use More Frequent Training Patterns Rather Than Once-Weekly Body-Part Training

For most people, accomplishing volume in somewhat more frequent patterns is easier and more resilient than training a body part only once per week. Preferred practical setup is about three total-body sessions per week; another suggested mixed approach is two whole-body days plus two body-part split days. If you only train legs once per week, that session should be very challenging and include quite a bit of volume.
