I have previously done the starting strength program, which puts emphasis on compound exercises with a lower body focus. Recently I have started commuting to work on my bicycle, and my commute includes a steep hill-climb at the end of the day. After that, the last thing I want to do is squats.
My lower body and core get a sufficient workout, so I would like to compliment this with upper body strength training. I have adjustable dumbbells and enough gym experience to train myself.
My question is, what is a good upper body focused strength routine (preferably requiring only a dumbbells and chin-up bar) for a cyclist?
