Today you’re going to revisit a workout from 2015t. Coincidentally, today’s workout was also Day 9 of last year’s fitness challenge, and is going to focus on full body strength.

Day 9 – It’s Eccentric! (Boogie Woogie Woogie)

There may not be any choreography or special dance for this workout, but you’ll feel like you’re creating your own!

Concentric and Eccentric contractions are two types of muscle contractions. The concentric contraction happens on the lifting or loading phase of the movement. The eccentric contraction is the lowering or deloading phase of the contraction.

This workout focuses on the eccentric phase of the exercises below. Eccentric loading helps to build muscle strength. The slow contraction puts stress on the muscle, thus making it work harder. As a result, strength and power gains can be made.

Do the entire sequence for rounds of 10/8/6/4/2/1. So on the first round you’ll do 10 repetitions of each exercise. On the second round you’ll do 8, and work you way all the way down to one rep.

Lower the weight (even if that weight is you body) for a count of 5 seconds for each rep. Lift the weight for a count of one. Watch this video for an example.
