@drgnslayr thanks for the note about gradual change. That could work for me.
I will make a comment about nutrition. I was so scrawny as a high school soph I could hardlyin walk and chew gum. Two years later I graduated at 180 and still very lean for my6' 2" build and we lifted constantly.
My frosh year at KU I ate on the training table. LTake that X Physical Maturity X increased Training X more and advanced weight lifting and I was a beast.very explosive and agile. (Not a ball player but our bBall bigs were just plain slow with little explosiveness. I KNOW the weight training is much better per coaches I know still at the DIv 1 level. I know the food back in the day was good, and I'm sure there have been improvements. You can make sure the athletes do the workouts and lift right-but the diet is still a wild card-not everyone follows the program to the letter.
