Speede science principle #1

Get results faster with Isokinetic Training

By offering perfect resistance at every moment, Speede’s Nemesis Mode taps into the power of isokinetic training. Studies have consistently shown that this intense, maximal resistance creates faster increases in strength and muscle mass. Speede is the first machine to make isokinetic training attainable for the average person.

Speede science principle #2

Rebuild muscle more quickly with Eccentric Training

Our Excentric™ Mode is based on a powerful scientific discovery: your muscles are far stronger in the eccentric, or “negative” portion of a movement, than in the concentric portion. Through eccentric training, Speede allows you lift heavy—safely—to activate your body’s true abilities and help increase your strength, flexibility, and sports performance.

SPEEDE SCIENCE PRINCIPLE #3

Stay flexible through active recovery

Science shows that rest is good, but activate recovery is better. Speede’s Recovery Mode helps your body heal through End Range Activation (ERA), which is proven to help you shorten recovery time, maintain flexibility, and nurture muscle growth.

The science to supercharge your training.
