The oblique muscles are an integral part of the core, helping you perform many basic movements. They also help you control your posture and pelvic position. Working on them will also strengthen your entire core. A strong core is essential for sporting performance, and can help you move heavier loads.
Static holds are also useful for developing strong core muscles. This is because the core is required to engage to maintain the body's position, which is crucial to holding an exercise. They can also help build joint resiliency, which is necessary for heavy lifts.
Squat static holds are isometric exercises that target the glutes. For example, beginners can use isometric bodyweight squats to improve their positional awareness. More advanced lifters can set up safety pins on a rack and squat against them, maintaining position of the legs. As a rule, isometric exercises are prescribed for 10 to 30 seconds.
