Sled Pushes Straight Arms vs Bent Arms
Arms straight is beneficial for acceleration simply due to the bigger stride length.
Arms bent gives you better leverage from a more tight, compact position allowing you to push heavier loads due to a shorter stride/range of motion, giving you a mechanical advantage.
Yes it’s possible to push heavy loads with arms straight, but the key is to maintain a neutral spine, most people end up dropping their neck and rounding their back to use their bodyweight as an advantage to push.
- Aways maintain a neutral spine
- Arms straight is better for acceleration/speed
- Bent arms is better for heavy loads
