FI bought a Total Gym using a Groupon Deal where he got a Total Gym XLS with the attachments and some extra dvds for half the normal cost. Our living room has been taken over by this beast.
I got to try it out and try the beginner workout on Saturday, and dang, did it work me! We were going to his Dad's for dinner that night- I had to actually bend over in the shower to shampoo and condition my hair because my arms were too tired/sore to lift above my shoulders. I went with wettish hair (gasp!) because I did not have the remaining strength to hold up the hair dryer. I had another workout last night (supposed to start it at 3x per week) and while several exercises were murderous, I actually am not in as much pain from muscle fatigue and soreness today.
One problem- one of the pins for our wing attachment came without the ball and spring required for the locking mechanism, so I can't do about 5-10 minutes of the beginner workout involving abs and pull ups. I've been compensating by adding other attachments that basically have me doing an ab roll, and doing more of the leg exercises, since I feel like that gets hurried up and out of the way at the beginning of the workout. I'll be alternating days with total gym with my actual gym membership (which runs out in two months) so I'll get in more cardio on those alt days plus some leg and back work.
Here's hoping I have before and after pics/success story to post in a few months!
