I'm thinking of doing various throws and tosses as well as different kinds of carries. So, things like throwing a tire like a discus, kettlebell tosses and pushes for height and distance, carrying stuff for distance or one handed or a slosh pipe. Stuff like that.
I haven't tried any yet, so don't know how much stuff like that affects your back, but I doubt it would do much to affect your legs.
Anyway, that's what I'm thinking. I'll be interested in what you end up doing.

Hack away at anything which isn't essential. Do what you love, and do it often. Fazc.
Everything competes for recovery so more assistance is not always the best idea. miked96
