Description

The TANK™ M4 continues the evolution of this unique push sled on wheels. The core technology that makes all TANK™ models unique is that unlike resistance sleds, they can be run indoors or outdoors on any surface without gouging. Also on all TANK™ models the resistance increases the faster you push it, so each user can choose their resistance on the fly, without stopping to load or unload plates. 

Resistance

• The wheel resistance or "braking" is on all 4 wheels, so if the push end rises up at high speed, the other end still applies the resistance. This eliminates the need on earlier models to load plates to prevent rising up.
  
• The resistance levels can be set at each end independent of each other enabling one resistance on the push and a different resistance on the pull
• All wheel resistance also makes  TANK™ M4 bi-directional, so there is no need to turn the unit around to revers direction

Features

• Safety - Resistance that feels dangerous can be backed down instantly during the run to al level that feels safer depending on the user's age, conditioning level, and fitness goals.

• The Experience - The feeling the resistance increased with speed cause a surprise "wow"reaction and a novel exercise experience that users love.

• H.I.I.T - This model enables High Intensity Interval Training (H.I.I.T) in which bursts of acceleration and speed for 14 minutes of a  TANK™ workout is the equivalent of an hour on a treadmill.
