I've completed three days of the 30 day shred and I'm finally starting to feel like I might actually be able to survive. The hardest part for me now is the push ups. I don't do the "real" push ups. I do what you would consider to be the "girl" push ups, which are hard on my knees. Minus the part where I'm sore as all get out - especially my thighs, I feel that I have more energy. I'm not sure that makes any sense. I wake up in the more in pain, but once I get moving I'm fine, I'm just attributing this to age. :) We'll see how I'm doing after a week of this stuff.
