Currently rehabing from a knee injury and need to build strength. I have heard everything from once to three times per week for how often to work legs. I am 35 years old and am not planning on doing any cycling in between workouts until I build enough strength to be comfortable on the bike. Obviously, I will be adjusting based on results but what should I start with? Is three times per week to much? Will once per week do any good? Would twice per week be the sweet spot to start with? Thanks in advance for any thoughts.
