One of the better works out I've had in my life was with Simon from Plyomax. It was a high-intensity bootcamp and always included plyometrics in the grueling workouts. I liked him so much that I took private lessons from him. We spent hours, weeks and months learning how to jump. I was definitely in shape back then (to my defence having a year old baby is the best thing in the world but reduces the amount of time I can train).
According to their website:
PLYOMAX is derived from two words: plyometric and maximum :
Plyometric training involves quick, powerful movements using a pre-stretch, or counter-movement that engages the body’s stretch shortening cycle (SSC). The SSC employs the energy storage capabilities and stimulation of the stretch reflex to facilitate a maximal increase in muscle recruitment over a minimal amount of time.
Maximum refers to the maximum speed, strength, power, quickness, agility, balance, stability, control, overall fitness and athleticism a person can possesses.
When attending one of Simon's fitness class you can expect to work on many components of fitness such as balance, coordination, agility, reaction time, speed, power and mental capability.
Simon is a great athlete and practices what he preaches. Check out Plyomax for a great workout.
