Wrestling is not a three months out of the year sport. Those who are standing on the podium after tournaments each week and earning a ticket to go to states, do not just wrestle three months. They put in the "off season" work by taking part in Freestyle & Greco practices and competing in the tournaments, making themselves better both physically and mentally.
If you want to see your wrestler improve even more, have them do the strength and conditioning that is offered after Freestyle and Greco is completed. (It runs throughout the summer and into the school year.) It gets tiring to see your wrestler put in the time at practice during the "regular" season, then come time to compete, they end up coming off the mat without scoring points, without taking a single shot, or winning. Have them make themselves not only physically stronger, but mentally stronger by having them take part in Freestyle & Greco and Strength and Conditioning throughout the summer.
It may not be something that your wrestler wants to do during their summer "free time", however it is what they need to do so they have less free time in the stands during the season.
