Red Bull Smurf Jack
Red Bull Smurf Jack
Same as the standard smurf jack, except high-tempo cadence at 2 or 3 times the speed of a normal cadence. Always done in cadence, no less than 20. 20 is challenging, 30 will take your breath away, and 40 would be a very high level of achievement. Heart rate spikes, so be mindful of what the PAX can handle.
