I doubt they will really do any weights he has problems playing with my 3lb weights. He only weighs 59lbs. He loves to walk an play ball. I was just a little older then him when I started building muscles up. I never used weights until I was a teen then I pretty much lived at the ymca gym. I just hope him exercising more and doing what ever they plan on doing helps him get more of a appetite and helps him grow within himself emotionally and physically
