So your body type is something that has been passed on to you at birth and shapes the way we look and respond to exercise and nutrition. If I go back to my original question of how much weight training should we do, then I think it is more appropriate to find out what works best for you and how you will respond.
If two people of different body types trained the same and ate and slept the same, there is a very good chance they would get different results. There is not one size fits all when it comes to training and also nutrition. But it is a question of assessing your goals, your body type, and working out what can be achieved and what works best for you.
It is because of this individual difference that so much speculation surrounds exercise,nutrition, the best exercise programme and diet. But I do not think there is one silver bullet.
