After years of back problems eg slipped discs and other problems I now work my back harder than any other body part.

I'm getting a bit elderly now, sob, and due to some sort of ongoing injury to my chest and shoulders I just can't do pull ups or up my weight on the bench press by any substantial amount, so I just do all sorts of rows. Seated, bent over, one arm dumbbells . . . I love em.

For the same reasons I've started squatting a lot more and a lot heavier. I'm starting to see why people get so obsessed with squatting!

My favourite muscle group though is my back, because that's where I've made most progress and even at my age still continue to make progress.
