I am a mother of 2 boys that wrestle (10 & 12). During the past year they have been on a very regimented and consistent weight lifting routine with their father. During the previous year, they worked out a little less frequently and a bit less structured. During each workout their father is with them supervising and instructing them. Until recently all of their weightlifting was done using primarily dumbells with none of the excersizes putting direct pressure on the spine. The logic behind using mainly dumbells was that it would help to force the boys to control the weight they were using while they learn the proper technique and speed for each exercise. They also do incline, decline and regular pushups with weights on their back for added difficulty along with pull-ups and rope climb. In my opinion this time with their father has been wonderful dad/son interaction time. The boys are eager (most of the time) to spend the time and energy in this area. We have seen an ENORMOUS difference in their strength and their confidence. Done correctly, I recommend this to anyone who has a child that is eager and the time to invest in it with them.
