Just wondering about some of the harder bent arm conditioning exercises on the rings. I'm not yet at the level where I can do these, except curls, which I somehow did one day to show off in front of friends the topic is just me wondering which exercise is working what and in which way, and whether some are more effective than others. As far as I know, each of these exercises are conditioning the following muscles: Curls: Chest, Biceps, Anterior Deltoids, lats? FL Rows: Lats, Posterior Deltoids, Biceps, Middle and Lower Traps and Rhomboids BL Curls: Chest, Anterior Deltoids, Biceps, middle back musculature? Anyways, just something I was thinking about.
