Plan acceleration and resisted-sprint drills around your training goal. This category includes sleds, parachutes, harnesses and belts for solo or partner work, depending on the model. Movement resistance is not measured identically across these accessories and does not replace specific change-of-direction drills.
A sled uses its load and ground contact; a parachute creates air resistance during movement; a partner belt lets the partner control the pull. Choose by available space and training method, not just product size.
For sleds, check permitted surfaces, load limits and plate compatibility. Not every model is made for both pushing and pulling. For harnesses and belts, check fit, connectors, cord length and elasticity; a harness alone is not a complete system.
Inspect attachments, seams, cords and structure before use. Keep the route clear and coordinate starts and stops with your partner, avoiding sudden jerks. Increase resistance progressively for controlled movement and respect both equipment and surface limits.
Only if stated in the product details. Check plates, belt, harness and cord separately in the package contents.
Do not assume a fixed plate-weight equivalent; resistance depends on the model and movement conditions.
No. Non-elastic systems also exist; check the exact description and do not substitute unconfirmed cords or connectors.
