i have finally found a reliable workout partner. he lifted alot in the past but quit due to lower back probs. he has been very careful since he started with me, doing very few exercises. mainly bench press, lat pulls, curling on the preacher pad and a few others.but, after only 2 wks, his back has started bothering him and he is leery of continuing. his back problems are bulging discs in L-5 and S-1. does anyone have any good tips in general and certain exercises that would minimize his discomfort while still allowing him to participate? thanks.
