Breaking a sweat can be done in Body Beast if you keep up with Sagi. Kind of weird since my core is already in pretty decent shape. I think Sagi put a great effort and his dedication is remarkable, but maybe BeachBody should have wait a couple of months and rehearsed a little bit more and take production into account, the rep count is missing sometimes. Chest was well worked, but I feel that the back was a little forgotten, Legs, it was hard but Beast Up Legs is even harder than this one. Different angles and exercises hit different fibers of the fan-shaped muscle.
