此处的Upgrade Sled-Pushes、 Optimize Form 分别如何理解？

Upgrade Sled-Pushes
Our unique design includes a sturdy, built-in bar that simulates sled pushing and pulling without needing the space to use a traditional sled. Multiple sled brake settings help coaches and trainers develop precise progression programs to maximize results.

Enhance Resistance Training
A parachute brake with multiple settings gives users the feel of real parachute resistance, perfect for resisted sprint drills without extra gear or access to a large track or field.

Augment Agility
Athletes can perform forward, lateral or reverse movements to maximize neuromuscular development and enhance agility. Full-length handrails offer stability as users switch rapidly from one phase of athletic movement to the next.

Elevate Sprinting
The 7-degree incline and natural ground reaction force are ideal for building strength and explosiveness in sprint training without changing the athlete's natural gait.

Optimize Form
The intuitive, effortlessly adjustable harness allows for a complete upper-body range of movement. Its unique design helps users refine form while coaches observe multiple sprint phases, adjust resistance and provide real-time feedback.
