Wow! Pretty much got a " butt kickin" on day 1. Hats off to the ladies of sts....I feel humbled! I tried to be conservative on my 1rms and still struggled.I Couldn't finish all the push ups and I was always good at them! It took me longer to get the proper weights so the program took me 105 minutes...geez! I am 64 but have lifted weights for several years so I was surprised at the diffulculty of meso 1. I have an autoimmune disease where my immune system attacks skeletal muscle tissue (polymyositis) but I am determined and will do cardio and abs tomorrow. I will be glad to get to meso 3.....shorter sets!!!
