High Volume Training (HVT)

High Volume Training is a weight training method that requires the trainee to perform multiple sets per body part. A typical HVT session will train a particular muscle group with anywhere between 10 and 30 sets per session.

The theory is that by training so much you are constantly stimulating muscle growth. Critics of the method argue that the body was not designed to be trained as individual units on certain days, e.g. Chest one day, legs another etc. This method requires the trainee to spend long periods of time in the gym. It does not allow for full recovery of body parts either.
The debate between HIT and HVT continues to rage to this day.
