Training frequency is an important factor in muscle hypertrophy. If loading the muscle with sufficient weight to increase protein synthesis is the key to this hypertrophy, why not apply the load every day so protein synthesis remains elevated. As long as your getting sufficient calories, then you will be in an anabolic state more often than if you were training every other day. Of course you have to adjust volume if you are training every day, and you have to be mindful that RBE may catch up with you a bit quicker being you are applying the load more frequently.
