Just a year ago I upped my raw squat by 8% in 3 months using a 90% weight for a set of 3 the first week, 2 sets of 3 the second week and set of 5 the third week and then increased the weight by 3% and repeated the routine weekly until the weight reached a point I was only able to do sets of 3 reps. I then took a light week and tried a new max the following week - +8%! I decided to change the routine and do a Westside box squat workout the next 3 months. The Westside program calls for a max day on various height boxes on Monday and using bands to accomodate resistance, a dynamic, low rep, 6-10 set for explosive strength, on Friday. I did increase all of my raw box squat maxes but, because they never do any full squats, I didn't feel ready to test my raw full squat right after the box squat routine. Instead, I thought I'd do a short (4 week) full squat program similar to the previous one and then try for a new max. Unfortunately, after the scond workout, both knees started to hurt and I was forced to cut my weights down to 40%-50% and start a 3 month recovery routine and do more stretching for my quads (hip flexors. It seems to have worked as I was able to do a good full squat with just 10# less than my increase 6 months earlier. Some master lifters never go heavy in their workouts, staying around 75% RM for reps, some do only sets of 2 with weights over 90% and some say that box squat routines work for them and spares their knees. As I've gotten older, I've found that squating twice a week, even if one day is heavy and one day for speed, is pretty demanding, as I also do benches and deadlift/back work once a week and, if I'm doing a challenging routine, I need at least a week for recovery. Any thoughts from other master lifters on their routines?
