I can't do squats anymore because it would take minimum 3 days, usually 4 days to recover from *any* kind of weight work. Just sore and legs would not respond on the bike. So now I just do plyometric stuff like box jumps (built my own 20/24/30 box), skater jumps, scissor jumps, etc. Normally I can recover in a day and I feel much more lively on my feet. Hard to tell on the bike so much, because I don't do much Z6+ stuff, but sometimes I'll look down and be surprised at the power I'm doing (for short periods). If using weights is too hard on the legs, try doing some plyo stuff, it's harder than it seems, and has made me feel better.
