Oooooooo can I join in??? Want a nice ass for the summer( think it really is asking the impossible...lol) does it work? Anyone seeing a change??? And sorry to be a bit thick but what's the difference between a squat and a crunch?? Is a crunch lieing on your back and 'crunching' up then putting your legs back straight??? Sorry I'm a bit dim, been a while since I did exercise....
