@XFactor posted:When you plan on implementing strength programs, and this is especially true if they haven't been as active, please please please don't do too much too soon. That is going to be based on the individual, and there's more factors involved than just that, but as a general rule, if you do too much too soon after doing too little for too long, you have a higher chance of getting hurt. Doesn't guarantee it, but, start it off slow if possible, and gradually build up volume and intensity.
This is great advice. My sons HS coach hit them hard on core stuff on the first workout in the fall and basically wrecked them for more than a week. My son was already working out regularly and he couldn’t hit for 3 or 4 days. The school trainer got wind of it and laid into the coach.
