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.
New Features on the M4:
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.
Three 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 reverse direction.
Features of All Tank Models
Safety Resistance that feels dangerous can be backed down instantly during the run to a level that feels safer depending on the user’s age, conditioning level, and fitness goals.
The Experience Feeling the resistance increase with speed causes a surprise “wow” reaction and a novel exercise experience that users love
H.I.I.T All TANK™ models enable 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.
Warranty 10 year warranty on frame and welds and 1 year on parts and finish on workmanship and materials
