Answer 1

9 rounds per day!

Answer 2

Sets are determined by your age and experience. Normally 3 to 5 sets should enough. It depends on wheather you are wanting to increase strength or just build muscle or both. Low sets and heavy weights for strength and high sets and lower weight for muscle building. There are a lot of considerations in this equation and your Doctor is one that should be contacted before starting any extra level fitness program. It is to ensure that you are healthy enough to workout.
