I found this chart on Facebook and started it about 5 days ago. At this point I can't imagine doing 250 squats but I'm going to work my way through this! Yesterday was on Day 5 and after work I met a friend for dinner and then ran errands and I was just too tired to do 70 squats but I plan on doing them today! Even if it's impossible to do 250 squats I'm still going to incorporate these into my exercise routine because just after a few days I could feel my behind and the back of my upper legs getting firmer! Those are my problem areas!
When you do them just be sure to not let your knees extend beyond your toes...that is bad for you knees!
