TorsoBurner® SpeedChain®

Set up: Connect the universal SpeedChain® segments to the handlebar with the quick links, and check every link before each session. Train in a clear area with room for the chains’ full swing in every direction — overhead, side-to-side, and through a full rotation.

Training use: Run the patterns shown in the videos — bilateral waves, overhead slams, rotational chops, torso twists, and 360-degree rotations. Start at a controlled speed and build toward full speed only as the pattern stays clean; the chain’s behavior tells you immediately when form breaks down. Work in short sets with rest, the way the demonstration videos are organized.

Care: Inspect the bar, links, and quick-link connectors before use and replace any worn component — every part of the system is available individually.

A full TorsoBurner® includes the handlebar, two universal SpeedChain® segments, and a chain carrier. The four chain levels differ in resistance; use the sport-specific ranges below to select. When in doubt, start lighter — segments swap in seconds.

Strong — Typically chosen by entry-level and senior athletes. Designed for any age athlete from adolescent to senior with below-to-average strength compared to their peer group, having no physical constraints, and capable of vigorous exercise intensity.

X-Strong — Typically chosen by varsity-level high school athletes. Designed for any age athlete from adolescent to adult with average strength compared to their peer group, having no physical constraints, and capable of vigorous exercise intensity.

Ultra — Typically chosen by varsity-level high school and college athletes. Designed for any age athlete from adolescent to adult with above-average strength compared to their peer group, having no physical constraints, and capable of vigorous exercise intensity.

Pro — Typically chosen by college and professional athletes. Designed for the elite athlete from late adolescent to adult with greater strength compared to their peer group, having no physical constraints, and capable of vigorous exercise intensity.

Muscularly mature athletes and those approximately 6’4” and taller should consider adding extensions for optimal training range and loading options.

• Commonly used for baseball and softball athletes adding rotational strength and core work to a throwing or hitting program.
• Commonly used for golfers and tennis players training the rotational patterns their swings are built on.
• Commonly used for coaches and facilities that want one rotational tool with four resistance levels, instead of four separate implements.
• Commonly used for existing SpeedChain® owners expanding into rotational work with segments that swap across the whole system.

• It does not diagnose, treat, or prevent injury — including oblique and trunk injuries — and it is not a medical, therapeutic, or rehabilitation device.
• It does not guarantee gains in bat speed, throwing velocity, clubhead speed, or any other performance measure; outcomes depend on the athlete’s full program, workload, and coaching.
• It does not replace a structured training program or qualified coaching and supervision.

This is training equipment for vigorous exercise, not a toy. The TorsoBurner® is designed for athletes with no physical constraints who are cleared for vigorous exercise intensity; anyone with a current injury, pain, or a physical limitation should get qualified professional guidance before using it, and it must never be used to diagnose, treat, or rehabilitate an injury. Inspect the bar, chain links, and quick-link connectors before every session and train only in a clear area, clear of other people, for the chains’ full swing path. Adolescent athletes should train under close adult supervision, start with the Strong level, and progress only when the movement patterns stay clean at speed. Stop if anything hurts.

Youth and growth-window guidance: athletes still developing should work under close supervision, with drill selection, chain level, and effort matched to age, experience, and health status.
