If I could find a hotel with dumbbells, that would be ideal. However, I'm limited in my choices because of location and especially because I can't spend over GSA perdiem rates

The circuits are something I've considered.

I am not familiar with all the exercises you guys are recommending. I better start doing some googling, I guess.

The TRX is a good idea, too, and something that I had thought about at one time but since have forgotten about. I'll have to look into that, too, and see what they cost (always a consideration for me). Got any recommendations for sources with good prices?

Specifically, the losses I referred to were decreases in my capacity to do the swings, mostly. Maybe the bodyweight circuits will do better for me in that regard.
