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 downβ€”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. - WE KNOW TRAINING EQUIPMENT - When you purchase Running Arms from Tumbl Trak, you’re getting a TRUE training product.

They keep the arms in an L shape and forces the runner to keep great form. ### ⭐⭐⭐ Review *by I***N on 21 May 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. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.id/products/255205886-runarms-running-arms](https://www.desertcart.id/products/255205886-runarms-running-arms) --- *Product available on Desertcart Indonesia* *Store origin: ID* *Last updated: 2026-04-23*
