Jeff Martin talks about the challenges of working with teenagers, and the changes that happen with growth spurts. Jeff and his wife Mikki run CrossFit Kids. In growth spurts, the bones can grow faster than the muscles, and kids that move really well can suddenly have trouble. Loading up these kids right after a spurt can possibly do more harm than good.
In addition to identifying the dangers, Jeff covers some remedial drills and approaches for continuing the training while acknowledging the changes.
