This really goes for all ages, but since you're asking, I think you should be lifting enough so you can do 3 sets of eight reps with good form (very important). And also, make sure you are doing exercises that are effective ( that work the most amount of muscle groups, in other words). Exercises like that would be dead lifts, bench press, military press etc. And by doing that, you should be seeing results in about 12-15 weeks (depends on how fit you are). Hope that helped!
I can lift 45 to 55 pounds I work out a lot.I think a 11 year old boy should be able to lift 25 to about 30 or 35
It all depends on genetics. Based by your weight you may not have much muscle, but if you can lift your weight or more you are in good shape. On avg a 112 person can lift around 70-90 pounds.
Let the 5 year old lift 100 pound weights and he will lose tons of weight
More than you can that's for sure
an average nine year old boy's weight is about 75 to 90 pounds
Depends..........
