So, as I'm only a beginner and am resting whatever I've managed to do to myself, my bench and row have taken over more than I've ever managed in the squat haha
I don't want to end up neglecting the legs so I've been doing leg extensions and curls on the machines, anything else people could suggest?
Just rest it for 2-4 weeks. If you are committed to the gym, your legs will soon be back up there, so train for the long term.
And think of it as a chance to make yourself look as strong as you are to the average civilian. So begin ARMageddon and enjoy it - guilt free - for a few weeks.
Think chest, chestanbize, chestantrize, bizantrize, backenbize. No legs.
