Stunning pics! Your advice clearly comes by experience, rather than book learnin' =).

I work construction, and that involves hours of cardio (the way I do it. I hate dawdling, and stay moving as possible), and, today, involved carring ~50 lb. toilet down a hallway (stepping from joist to joist - the flooring is my task on this job) between my legs.

Trust me, tasks like that work muscles you don't even know you have. And that's a good thing about what I do. Not all jobs are so demanding physically, and when I have extra juice at the end of the day, I do some squats, leg lifts, pushups, etc.., just using body weight, in the morning before I go to work.

Amongst the most valuable and challenging body weight exercises involve pullups, which can be done variously to work different muscles, by for example, twisting from side to side and raising the knees above the waist to work the obliques.

One drawback to using 8 lb hammers to do my workout is handedness. I almost never wield a hammer with my left, so naturally my right develops more. sigh.

Nothing's perfect, but lotsa stuff is better than nothin', and better is the enemy of good enough.
