Plyometrics are powerful movements done very quickly at a maximal effort. We talked about their importance during mountain biking here:

This program is designed to fit around your current training program, with some hard workouts swapped for plyometric exercises.

This program isn't designed to smash you or grind you in to the ground--it's designed to give you gradual progression through to an intermediate plyometric training load.

This program also contains set testing days--you'll test your performance in the beginning then again at the end. If you're combining all of your training modes appropriately, you'll see an improvement in your plyometric performance towards the end.

Combined with the right types of aerobic training and skill training, this should help you to ride smooth and faster out on the trails!
