I've bought a set of weights from Argos last year, and I try and incorporate strength training into my daily exercise regime, but I'm not really seeing any gains from it. Motivation in the long-run really is what I lack with increasing muscle mass.
I'm slap-bang in the middle of the healthy range (21.4), but I'm not toned. I'd love to be able to get a bit of muscle and boost my upper-body strength, but I only ever seem to focus on cardio workouts and calorie-burning exercises.
