Revolutionary, High-Intensity, Low-Impact Workout.

Without getting too technical, you only get what you give. Speedflex machines respond to you. Suitable for anyone of any age or fitness level, Speedflex enables everyone to exercise at high intensities, but at levels set by each individual. This coupled with the added benefit of little (or no) post training muscle soreness; Speedflex is efficient, enjoyable and delivers a cardiovascular and resistance workout simultaneously.

Speedflex machines have a free motion bar which, unlike traditional resistance exercise machines, requires users to apply force through an entire exercise, as opposed to force in one direction, followed by a controlled movement back to the starting position. This means that even the most basic of exercises will become bigger and more complex, requiring the use of opposite muscle groups.
