Increase the sets, and number of push-ups in each set as strength increases. Lifting small weights can also increase arm strength. These can be used at home, which is very convenient. Weight training with larger weights can be done in the school weight room, or a gym club. It is best to get the advice from a weight trainer.
Crunches are a great way to increase stomach strength.
By doing crunches the abs will become stronger. This will help in many cheerleading activities from stunting to jumping. Increase the sets, and amount of crunches in each set as strength develops. It is very important that cheerleaders be flexible. This means taking the extra time daily to stretch out.
