yesterday when i said i would try imax 2 no one warned me! LOL. that was the hardest one so far. Is there a secret to the airborne jacks? will it just get easier as the weight comes off or is there something i need to do, like tighten my abs (which I dont have yet) My shirt was soaked and i was sweating like a pig. My youngest son kept saying "ma, you are sweating really bad!"
