I went here while I was home for Easter with my mother and sister in law. We are all different fitness levels but were able to get through the workout with the support of Dan and each other. The curved treadmill was tough but not unbearable- obviously self paced as there were no on off buttons. The TRX and weight training stations were my favorite. Dan will switch the workout for different days. Ours was all arms and shoulders and some squats. The air bike was a nice cardio addition- the more you push the better the breeze. I also like how the stations would stagger- strength, cardio, strength, cardio. All around great workout. I like the interval concept (multiple intervals of going all out, with rest periods in between) because it forced me to push myself but not get overwhelmed mind or body like I usually would over a long period of workout time. The abs at the end were another awesome addition but challenging. Unfortunately I live in TX but my mom bought a package (flexible packages) and has loved it since. Definitely stopping by when I return home. Thanks Dan!
