Hi Keith and Everyone. New here. Just got back into weight training after 13 years off. Due to a bad back with degenative disc disease, and arthitis. Pretty much staying away from lower back training. However, I picked up some dumbells bout 4 months ago, took it slow, and am seeing results I didn't know possible. I won't ever be massive, but the strength gains after 13 years is something I thought I could never do again. Do quite a bit of following Keith's recommendations on slow and steady. God is good!
