## Features

- INNOVATOR SPOTLIGHT - Jen Dodson, a multifaceted individual with experience as an athlete, coach, and parent in the gymnastics world, identified a recurring issue with running technique during vault rotations. Determined to find a solution, she conceptualized the Running Arms—an ingenious tool that resonates with athletes who thrive on kinesthetic learning. This idea caught the attention of Tumbl Trak Founder, Doug Davis, leading to its successful implementation.
- IMPROVES ARM POSITION - Most young athletes need to be reminded of how important their arms are for speed and power. Once in place, the Tumbl Trak Running Arms position the arms at a desired 90 degrees.
- KEEPS ELBOWS FROM CROSSING BODY - If your elbows point outwards, that means your arms are crossing your body, which actually slows you down—you won’t be able to get the momentum you need.
- SMART DESIGN - The simple design uses a length of soft, stretchy lycra that wraps around the elbow, held in place with comfortable, stitched loops on the thumb. Adjust the length for different sized athletes using the Velcro tab on the back.
- OPTIMIZE RUNNING FORM - Promotes a smooth, fluid running motion that can help track and field athletes conserve energy and run more efficiently.
- WE KNOW TRAINING EQUIPMENT - When you purchase Running Arms from Tumbl Trak, you’re getting a TRUE training product. Coaches, former gymnasts and industry experts make up the Tumbl Trak Staff which has been making the highest quality products for 30 year

### ⭐⭐⭐⭐⭐ Excellent
*by J***D on October 2, 2025*

Great for my athletes to help keep them form together

### ⭐⭐⭐⭐⭐ Great buy. Could be a little cheaper but oh well they work
*by C***N on June 18, 2025*

These work just as good as the more expensive set. They keep the arms in an L shape and forces the runner to keep great form.

### ⭐⭐⭐ 90 degree perfection
*by I***N on May 21, 2025*

The straps work but they slide off if the athlete is sweaty or has on long sleeve shirt. It does help keep their arms at 90 degrees. It worked really well for the girls that I was teaching how to hurdle. They did not know what to do with their arms.
