Saturday I did Ride Extreme followed by errands and chores. Sunday was a Get Glutes inspired total body heavy weights session followed by being lazy the rest of the day!
I have noticed my butt getting rounder and my sister mentioned something about how my shelf has gotten bigger when we were trying on jeans the day after Thanksgiving. DH also seems to like it. My problem is I still have fat covering it so it probably could look better if I could eat right and get rid of the fat. If you could do bodyweight hip thrusts and glute bridges (double and single leg) I bet you could see some difference. Might be tricky right now to do those until your back heals more.
I did try the back extension machine over the weekend. When I did the flat bench, I noticed it most in my hamstrings and low back and could definitely see how this could cause back problems if you already have them or don't pay attention to keeping your spine neutral. With the 45 degree, I didn't notice it as much in my back but mostly in my glutes and a little in my hamstrings. You would need to be careful to keep in your spin in neutral and not hyperextend at the top. Since I am not a doctor I am not saying that you should be ok, just letting you know how I felt the exercises working my muscles. If you put the machine together and try it, would you still be able to send it back?
Glad you got to do some lifting. I did just the 2 set premix and could not do the finishers on my toes and struggled even at my knees. Don't know how Cathe did it on her toes other than she is a machine. Have a great day!
