I've been trying to dig up some info on line about lifting weights and kids (particularly my 14 1/2 year old son) but figured maybe someone on here had some personal stories or opinions that could help me guide him.
As mentioned above, 14.5 year old boy (15 in late June), somewhere around 6' tall and 175 pounds (both roughly 90th percentile). Plays football and baseball and has been doing an off season training program for the last year or so with a personal trainer/group type training. He transitioned from the middle school group to the HS group after football season. He is a summer birthday and would fall on the older side of the grade, so physically he was ready for it I have no doubts, plus maturity wise he needed to be in a group with older kids as opposed to some of the 6th graders that were just starting in the middle school group.
Anyhoo, the middle school group does some light dumbell type stuff as well as conditioning and body weight resistance but little to no traditional strength training (ie bench press, squats, etc..). It wasn't that long ago that he was all excited because he finally got to 100 lbs bench press (I'll say just before Christmas), now he's already transgressed to doing 135 lbs 2 times (they have to do it 3x consecutively for it to be considered their high mark FWIW) needing the spotter on his 3rd attempt. They just started him on squats last week and for now its just the bar (45 lbs) while he works on his form.
I have total faith in the program and gym that he's going to, they work with a ton of young athletes and all of my nephews have gone thru the program as well as my father used the couple who runs the gym as his trainer when they were just starting out. But rarely do I talk to them, its mostly just drop off and pick up an hour later, so I guess what I'm looking for are what are good goals for him? They have a chaulk board on their wall where they mark people's personal bests, but it doesn't start until they cross 185 lbs. My son who hated the idea of doing the training when we first signed him, there were actual tears shed the first day has fallen in love with the idea of hitting that mark by mid summer. I don't think its anyone in the gym pushing him that direction, I think he found a personal goal which has always been a struggle for him in the past. I'd love to see him hit that mark, and know he will someday, but by mid summer (start of football) seems like it would be uber aggressive and possibly not in his best long term interests. However, rarely has he set goals like this for himself, so achieving this would be a huge boost of confidence.
I've seen online that the average 14 year old boy can bench 50-80% of their weight, at 175 lbs, that would be 140 lb bench press and I have little doubt he is going to be there by the end of this month, heck maybe by the end of next week. Is there a good target to aim for? Is there a safe zone that he could speed pass? I have tried to remind him that with things like benching and getting stronger, its not about competing against someone else, its about competing against yourself and bettering yourself. Baseball season will kick into high gear here in about a month, right now he goes to training 3 x a week, baseball, school and math tutoring might limit that to just once or at most twice a week here soon.
If anyone has advice, I'd love to hear it. Cautionary tales, what to say when he hits a plateau aside from the obvious "its just a plateau"
