Name: Tim and Renee Keppers Favorite Exercise [Tim] Burpees. I think part of the reason is everyone else hat3se them so much. [Renee] Deadlifts are my favorite but I really do like wall ball and burpees. With burpees you can at least lie down for a second or two to rest. Wall ball…you know your butt is going to be sore a few days and that’s a good thing. Least Favorite Exercise [Tim] The rower! Don’t like it! Never will!!! [Renee] I hate snatches. What I love about IST [Tim]
