Squat This Way If You're Training for Athletics w/ Cal Dietz 

In triphasic training the final phase is French contrast training, this is a really great way of training.

The best reason to do strength training is increase muscle activation. The same muscles as in the athletic movement. Angles do indeed matter. But so does contraction type, contraction speed,... In my experience some exercises (bilateral BB squat) NEVER overload/activate the muscle as much as other exercises SSB split squat or flywheel squats. But more important : Gravitational loading is not good! Everyone uses weights to create gravitational overload because it's a very practical and simple way to create overload. But it's the wrong type for sure. Athletes want to be faster /more powerfull. So acceleration of movement is the goal. The resistance is inertia! Very important: Inertia is the resistance. And it's dependend on mass but not gravity! F=m*a! NOT F=m*g So any additional gravitational load is bad. Exercises like olympic lifts are a combination of gravitational and inerational overlaod! But the more weigth one uses the more the gravitational resistance. Flywheel training is pure inertial resistance. It's much more effective or evelopting strength/power than traditinal BB exercises.

i'll look more into this, thanks @@Leonidas-eu9bb
