*VersaClimbers that come with Cross Crawl are as follows:
H, HP, SM and SMA. All others can be added with this option
as an upgrade feature. Please contact us for details.

What is Standard Climb Pattern?
This is a pattern when your elbow & knee maintain equal distance apart both on the up stroke and down stroke. For example, when you climb a ladder, the hand that moves up a rung is followed by the foot on the same side of the body.

Standard Climb pattern, the Elbow and Knee stay equal distance apart in either direction.

Super-Strengthen
The Para-Spinal Musculature
THE ARM AND LEG CLIMBING MOTION ON THE LINEAR CROSS-CRAWL VERSACLIMBER SUPER STIMULATES AND STRENGTHENS THE PARA-SPINAL MUSCULATURE(7)
Author, Francis Xavier Murphy,

Coretraining of Dallas, Dallas, TX. Aug. 1999 The linear cross-crawl motion on the Versa Climber super-strengthens the para-spinal musculature due to superior neurological and muscular stimulation of the crossed extensor reflex(1)(3) and spinal sway(6). The para-spinal muscles are involuntary muscles that work together through automatic feed forward(2)(4) (predictive mechanism) and feed back(2)(4) (corrective mechanism) systems in stabilizing the spine and posture in relation to all physical and balance demands of the body. During the crossed extensor reflex(3) neural-connections are made to the other side of the body in the opposite limb that cause opposite muscle contractions on the other side of the body. Feed forward(5) and feed back(5) mechanisms are in process when cross-crawl arm and leg climbing on the Versaclimber. All the major muscle groups in the body are actively relaxing, and contracting simultaneously at various speeds, forces and range of motion. During spinal sway(6) the para-spinal muscles are stimulated through a range of motion, which naturally causes them to contract, and relax in feed forward(4) and feed back(4) to accomplish stabilized posture while the body is in motion. Repetitive spinal sway(6) is produced in the cross-crawl arm and leg climbing motion on the Versaclimber and can be performed at variable speeds, forces and range of motion. As these phenomena occur, the central nervous system senses this, contracts and relaxes the para-spinal muscles automatically, proportionately and appropriately to stabilize the spine and posture in the feed forward(4) and a feed back(4) cycles. On the Versaclimber the linear cross-crawl arm and leg climbing motion depending on the speed, forces and range of motion performed, will more safely and effectively strengthen the para-spinal musculature, proportionately and appropriately.

One MET is equal to an oxygen consumption of about 3.5 mililiters per kilogram body weight per minute.

Since METs include body weight as part of the equation, it is a universal number and one need not worry about the effect of body weight.

As a practical tool, the MET allows for a general comparison of differing activities and relative intensities. Activities are often classified as light, moderate or vigorous, but may also be in any one of the three categories based on how hard the individual is working relative to their capacity.
