I'm about 5 months removed from ACL reconstruction using a hamstring graft and am well ahead of schedule with my strength and endurance. However, my physical therapist tests my injured leg vs. my "good leg" (also tore that ACL in 2005) once per month and I've been lagging in hamstring strength in both legs. My hamstring strength in my non-surgery leg has been between 59-66% as strong as my quad strength in that leg while my surgery leg has been 52-54% in that regard. My PT says it should be between 60-80%, so I'd obviously like to build that way up in both legs so I don't tear it again.
I've pretty much had the training wheels removed in my physical therapy for the past two months and have made decent gains in the weight room and running. I've been hammering my posterior chain, or so I thought, but my test results haven't really budged. Main lifts I've been focusing on have been traditional squats, deadlifts, RDLs, GHRs, Bulgarian split squats and hamstring curls. I've also started some glute activation work based on an article I read on this site ("Dispelling the glute myth" I think it was).
I have been squatting twice per week and deadlifting once per week. I also started working some power cleans into the mix, though with very little weight. My question is, would it be wise to replace my squat days with deadlift days, or at least cut down the quad-heavy exercises while I try to build up my hamstring strength? I am just brainstorming here. I have been working a 2:1 or sometimes 3:1 squat-to-deadlift routine for the past 4-5 years on average. I just always assumed programs should be squat-heavy.
