My son just turned 13 and has been strength training for about a year now.
He usually works out with a personal trainer 4-5 days per week (Friend of the family so it doesn't cost us anything)
His daily routine usually goes something like this:
10 min - Ladders, hurdles and box hops followed by 20 push ups and 40 crunches.
40 min - circuit training, 3-4 exercises at a time. 2 sets of 20 or more reps. Usually 2-3 circuits
10 min - Ladders and hurdles followed by 20 push ups and 40 crunches.
My question concerns the circuits. A sample circuit might be: 1)Seated row, 2)Walking lunges with dumbells 3)Overhead tricep extension and 4) some form of abdominal work. The exercises are always varied and I believe most involve compound movements.
He loves to work out but I have worried that he is starting to young.
Anyone have any thought on this subject?
