static hamstring holds
Because you must hold your body still in order to lift weight, static holds are particularly effective for strengthening your core. You'll also be less likely to get injured during heavy lifting.
Static holds are also beneficial for developing your posture. Correct alignment is essential for achieving the best posture and maintaining balance. A neutral back alignment and shoulders over hips are vital to maintaining the proper posture and holding position. These exercises also help develop muscle memory.
Static holds can be a great way for you to increase your strength and challenge yourself mentally. While you may want to get out of static holds quickly, it is important to keep your eyes on the goal. These require you to be focused on one task for long periods of time and give you a goal.
