Do you ever train FULL upper body?Overall, the entire upper body musculature (delts, pecs & lats) has shown to display a ~50:50mix of type 1&2 muscle fibres. This suggests that when training upper body, BOTH high+low speeds & heavy+moderate loads are beneficial for growth. Thus, to set up an effective upper body workout, selecting 2 lifts/muscle (compound & isolation) will allow to work BOTH heavy & moderate loading. For heavy exercises, compound lifts allow for most “bang for buck”.
