Wow, you guys know a lot about working out and getting in shape. Does anyone have any recommendations for hamstring toning exercises that are easy on really bad knees? I know squats and lunges are ideal, but just three of either makes my knees feel like they're about to completely give out. I don't want to be super jacked, but I do want to actually look like I, you know, have hamstrings. And if it gets rid of cellulite, even better. Also, I had two abdominal surgeries when I was a teenager, and I've got a decent amount of scar tissue because of it. Is there any hope that I can ever get a super flat stomach with that scar tissue, or is that just a pipe dream?
