 I was shocked by what a strength difference there is between my two legs. So I'm a right leg amputee, meaning that my left leg is obviously going to be stronger. It overcompensates for my amputated side quite a lot. So this is my first time using this machine, and I just wanted to test it out. On my left leg, I was able to easily do sets of 90 pounds, no big deal. So then I switched to my prosthetic side. I tried it at the same weight. That was a no-go. I brought it down to 60, also a no-go. We tried 40. I could get a couple reps, but it didn't feel good. So I had to go all the way down to 30. I always knew that this side was significantly weaker, but I had no idea that it was less than half. That thing I will definitely be working on through strength training. It's never going to be even, but if I can strengthen my prosthetic side, that will help prevent injuries and keep my body stronger and safer.
