Take group on a 400 m run stopping every 25-50 yards to practice a skill ex: 10 airsquats, push ups, tuck jumps, jumping jacks etc. Make sure for safety that there is a trainer at the front and end of the group.
Tarzan Swings: Align Bars so that they create a line long enough for athletes to get a few swings in a row. First have the athlete hold onto the bar as if they were going to do a pull up with both hands overhand and thumbs around the bar. Have them side shuffle down the bar until the reach the end of the line you have created. If that was doable for them have athlete stand underneath bar with one hand on each side of the bar. From here, they will need to pick up their feet and move one hand along the bar followed by the other hand, swinging hand over hand creating a Tarzan like motion.
Each Round Push a Sled or Box 5m. (Athletes may have to share sleds. These should be short easy pushes so that they are able to get back to work on pullups and squats. )
