I've been a long time lurker here... nearly got up to level 4 once (completed level 3 in time) but never been able to keep a program going regularly for more than a couple of weeks (usually I end up getting sick - don't know if its connected to the exercise).
Anyway I recently had some back problems and visited an osteopath (in the UK - I think this is closer to a chiropractor in the US but chiropractors here are a bit different). The manipulations and such helped but he said I have a tendency to roll my shoulders forward and hunch up. To counteract this I am stretching my pecs several times a day - and would like to start exercising again properly. He said simplefit type exercises were fine, but recommended adding a pulling exercise (he suggested bent over dumbell rows I think) to counteract the effect of pushups to develop the front of the chest and pull me forward.
So I was planning to get some rings and do body rows - I was thinking of doing same numebr of body rows as pushups and leaving out pulls/chins for a while, then start to put them in again I guess.
Just wondered what people thought about this - whether body rows are the best thing to get this effect, whether I should just add them and keep the pulls etc.
