Squats are always a challenge and weighted ones I don't think I can do because of back issues. I used to do the leg press and because of cycling could easily do 250lbs+. It has been quite a while since then. However, I do lunges now and I still hate those.
I just finished my free weight/resistance band training this afternoon and got even farther than before (35 min of 45 min). So still getting there. I'm at least keeping up with the reps and exercise. I had a vegan protein smoothie before that and am feeling good (although my arms are like rubber right now).
Just have to keep at it, even the exercises we don't like!
