I've never been able to do squats because I have bad knees. As as in life, my bad knees that prohibit me from doing certain exercises are partially due to my weight! #catch22 There are so many aerobic moves that make my knees do nothing but click, and my really bad knee will sometimes give out on me. So, that brings me to my new purchase. I bought the DBMethod machine. It is essentially to help you do squats while keeping the pressure off of your joints. But it is an overall aerobic workout (so it says) and helps with your pelvic floor (again, something that not only age but weight destroys) I did 10 the other day and my legs were like jello after, I couldn't walk, LOL Today I did 30. I think my form is correct, and I could feel the burn in my thighs. (again, I hope that is what I should be feeling, lol) I will go up a little each day until I get where I should be for an ideal daily workout. I can be the guinea pig to see if this machine is worth the money, lol. It's small,
