Unless you are not on gear I would not recommend such hard workout. Too much of everything.

Too much doing back and chest on the same day. Forarms and calves are fine because its very hard to overtrain them. Almost every minute your using them throughout the day so they have a higher resistance. To decrease the time you could take shorter breaks in between sets.

Im on my 5th day of a 2day split for this workout and another for Biceps, triceps, and shoulders and honestly i feel great. My question was just if i was taking to long in the gym to finish this particular routine. Was wondering how long ya think it should take.
