I'm at a year, have resumed weights, cutting the leg weights in half for now. I haven't resumed squats, dead lifts, but have been benching since about four months in.
I decided to resume my usual three sets of four exercises. I haven't done progressive since I was throwing the shotput in high school, just do 3 sets of 8 of everything. No belt, wrist anything, always wanted the full stress to be handled by my body appropriately (and not to lift something with aids).
I started very light with benches, 170 (3 X 8 ) at four months, very light with leg presses at 190 (3 X 8 ), curls at 70 and other exercises to avoid being bored (lat pulldowns, etc.) mixed in. All bracketed by elliptical and the bike or treadmill (walking) and calisthenics. Then stretching to cool down.
I'm now at 225 bench (3 X 8 ), still low on leg presses but high on reps - 250 at 3 X 30, and other exercises as noted above, but with about 20 pounds more per exercise. Running on the treadmill and have added about 15 minutes of heavy bag work.
Before the OA, I was at about 250 on the bench, about 450 - 500 on the leg press and other exercises mixed in, with all reps at 3 X 8. I also played soccer, basketball and did martial arts at night.
So not back to as before, but working close to it on the arms, looking to get back to soccer and maybe basketball (a friend of mine just tore his achilles playing hoops, but that can happen anywhere), but I probably will limit my leg presses / squats, etc. to less weight and more reps.
I started push ups and pull ups after about five months after outpatient PT, stayed off lunges (my stabilizers were too weak) and also made sure I added my PT exercises to my regular workout, since I had neglected my core too much in doing my regular workouts.
