Product Details

Use the Lifeline Chest Expander to add progressive variable weighted resistance to your upper body strengthening programs. Increase the range of motion and positioning of flies, pulls, curls and presses to strengthen and stretch pectoral, deltoid and arm muscles. A modern take on the classic tool designed for the original "strongmen" and bodybuilders, this upper body strength training device offers continual resistance and the ability to target specific muscles for rehabbing upper body injuries and creating increased flexible and mobility.

Incorporate up to 90lbs of peak weighted resistance by adding or removing up to three (3) 16” cables using Lifeline’s patented Progressive Resistance System. Interchange the cables to customize the resistance and progress in weight as you get stronger.

Resistance training uses resistance or force to induce muscular contraction, which builds strength and anaerobic endurance. Resistance exercises also help you increase bone density, improve metabolism and decrease your risk of injury. At Lifeline, we provide resistance training equipment that is both innovative and mobile to make your workout routine both effective and convenient. By doing so, our products are easy to use and can provide significant benefits in overall health and well-being by increasing bone, muscle, tendon and ligament strength.

Up to 90lb Resistance: Interchange Resistance Cables from 30lbs to 90lbs peak resistance. Add up to 3 Cables to equal 90lbs weighted resistance: 30lb + 30lb + 30lb = 90lb weighted peak resistance.

PROGRESSIVE RESISTANCE SYSTEM- Chest Expander utilizes Lifeline’s patented Progressive Resistance System which allows for resistance weight level interchangeability. Lifeline Resistance Cables are color-coded to easily identify resistance level (10lb -100lb peak resistance) and our patented cable pockets incorporated into the design allow a simple interchangeable process to add/subtract weighted resistance.

LIFELINE RESISTANCE CABLES – Designed using Lifeline’s Progressive Resistance Systems for resistance level interchangeability; the cable’s plugged ends safely, securely and easily fit into all Lifeline’s patented resistance cable pockets. Three R3-30lb 16” Resistance Cables are included here, however additional cables are available: 30lb, 40lb, 50lb, 60lb, 70lb, 80lb or 90lb weight levels. Each cable is color coded by weight (30lb – 90lb) for quick resistance level identification during interchange and are 16” long to accommodate a wide variety of exercises for everyone from beginners to advance users.


  • Three (3) 16” Resistance Cables – R3- 30lb each
  • Two (2) Chest Expander Handles

Cable Length: 16” Long Cables

Cable Resistance: Add up to 3 Cables to equal 90lbs weighted resistance: 30lb + 30lb + 30lb = 90lb weighted peak resistance

Each resistance level is defined as maximum force when the cable is stretched to 3x the original resting length. We strongly suggest never stretching cables more than 3x the resting level. It is a good idea to replace your bands every year, depending on use and wear - and Lifeline's interchangeable system makes the process convenient and easy!
