In addition to my butt qualms I am also having serious other pains. I moved 3 twin pillow top beds including box spring and bed frame by myself through the house. I think I tore something between the arch of my foot and my inner ankle. Then I spent half today on my knees rearranging the girls' play room and now my knees feel like there are no ligaments to separate the bones from rubbing together. Yikes!
So, opinions on exercise please. Longer time with steadier pace or short and furious? Also, how long should each session of weights last? Right now I'm averaging between 15-20 minutes. Give me your wisdom!
