and I loved it! my ass muscles started to lock up though. I did 5 down and back 20 yd sprints with 180 on it after a dynamic effort leg workout. I finally got a chance to workout at this gym that has safety bar, trap bar, chains, prowler, sled, tires, etc. I am hooked.
Awesome dude. I am pushing mine for the first time as well this week. I'm thinking 10 x 30m with 90 lbs added, alternating high/low handles.
good luck with that! Your mind will want to do it but your leg muscles want to give up way before that.
