Do these three isometric holds to increase your strength

Between all the treadmill runs, the functional warm-ups, the weight-lifting and the foam-rolling, it is important not to forget the simple magic of an isometric hold. But isometric holds are a vital part of unlocking the body, and the amount of time you can hold them for, is a marker of that increasing strength over time. There are three ways in which muscles move: eccentric, which is when the muscle lengthens in an exercise; concentric, which is when the muscle contracts, and the last one is isometric, which is the hold. Hollow hold: Hollow rocks are a popular and intense ab exercise for core strength and for some, the hollow hold is a good place to start training for hollow rocks. Isometric push-up hold: For those who are aiming to add an extra challenge to their upper body routine, the push-up hold is the perfect exercise to do, especially after a demanding push day.
