Congratulations on the weight loss . . . that is truly amazing. Your loose skin is a small price to pay for the years added to your life and your healthy life style. Congrats! I apologize if I offended you with the pic.
I occasionally use free weights for different strength training routines. To be honest, I like using weight machines better, but I do use free weights to change up the routine.
I have a lot of loose skin I'm trying to tone, since I've lost over 180 lbs. I have bat-wings.
