Age doesnt nessecerily have a huge factor on how much some one can lift. The factors that you should be focused on are the size of the 14 year old, does it hurt to lift it, how many reps is he/she doing. Ive seen 14 year olds that are really meaty and buff and ive seen some who dont really have strenth to them.
Regular exercises are the best way to prevent flexibility issues because it helps keep muscles healthy and in good shape. For that reason, it is not as probable for muscles to get torn down and for people to experiences with flexibility if they work out regularly.
