I don't work out often enough as I wish I should. Life, beer, video games get in the way in that order. I am 6' and 185lb so it could be worse. I try to walk on my treadmill more than once a week but realistically it is once a week. 1-2 miles depending on how I feel. At least I use it. I have a set of those cheap one handed dumbbells from many years ago and I use them twice a week. A usual session for both of my arms are 3 sets of 20 bicep curls, 3 sets of 20 One-Arm Shoulder Presses, 5 sets of 20 one-arm bench presses while laying on my floor. I am sure all I am doing is burning my beer and junk food off but that is okay for now.
Maybe this new years resolution I will work out more and not follow through with it like every other year.
