6 x 5 Minute Rounds on a 300lbs Thai Bag?.

[TheGreatBoxer]

Is 6 x 5 Minute intense rounds on a 300lbs Thai Bag a good training technique?.

Its not the size of the bag, or the number of rounds or the length of the rounds ---- but the quality of the rounds.
You could do better on a 80 lb. water bag.
