Looking for some help here. My daughter has really acquired a love for softball and is really good at it. Her problem is that she is very slow. One reason is that her stride is really short. I am looking for some drills to help increase her speed overall, but also to increase her stride. I am planning on having her use the stairs two or three at a time for the stride issue. I also think some squat jumps and such may help. Looking to really increase her speed during the off-season. Any help would be appreciated. Any other exercises to help her softball or basketball would be greatly appreciated. No weights as she is only 11. Thanks.
