I'm a roadie (as in sound engineer) for an events company; I weigh 280 and I seriously need to lose weight. However, since I've started this job a little under a year ago I can now touch my toes without bending my knees and I can lift myself onto the back of a truck and do 25 more press ups than I could do before.

The weight of some the flight cases we lift is quite big. I lifted a box of PA speakers up 2 flights of stairs the other day cos the venue's elevator had broken and when I got to the top, read the tour label and it weighed 70kg (154 lbs).

Apparently, we're not supposed to lift anything above 25kg (55 lbs) but how are you going to gain any muscle if that is the maximum weight you lift.
