Plyometrics = Jump Training

Above are some specific Plyometric exercises for track cycling - image was extracted from the book "Jumping Into Plyometrics" by Donald A. Chu, PhD, 2nd Edition. link

Plyometrics or Jump Training is defined as exercises that enable a muscle to reach maximum strength in as short a time as possible. This speed-strength ability is known as power ( Power = Work/Time). Power is the ability to do strength work at an explosive pace.

Before starting Jump Training, one must have a solid base in Strength Training, which is achieved by lifting weights. Lifting heavy weights develop force (muscular strength), which is needed in jumping since muscle contraction is involved...... more info here.

Advance training would include a combination of weights and jumps, such as using a weighted vest.
