You could also stretch one band between two trees or poles and have a friend place one of the 10 pound weights in the center of the band, pulling it back as far as possible (lke a crossbow). Have them let go, and try to catch the weight between both palms as it shoots towards you. This will give you biceps.
I unreservedly apologise for my troll like behaviour. As everyone on here knows I NEVER engage in trolling and feel I have let everyone down by engaging in it for the first time ever. In my defence, I was going through some shit at the time, my circumstance had changed and I had fallen in with the “wrong crowd” (Matt Phillips).
