Force is not just expressed concentrically. People tend to forget about isometric and eccentric strength, but they both play critical roles in overall strength development as well as injury prevention.
We’ve tried to get creative in adding more tempo work into the program. Some examples would be;
3 second eccentric + 3 second concentric RFE Split Squats
5 second eccentric + 5 second isometric Push Ups
Eccentric Only Slideboard Leg Curls
Eccentric Only Chin Ups
We could go on and on with examples, but the moral of the story is that athletes need to train more then just concentric strength. Add some isometric work. Add some eccentric work. And do it consistently.
