5. Let your glutes rest — do a GLUTE BRIDGE
Sitting all day in an office can deactivate our glutes which slows down the rate at which our body burns calories — the metabolism. The hip extension in the glute bridge exercise makes the butt work and it can also open up any tightness from long days of sitting. Leave your arms along your sides, squeeze your butt muscles to lift your hips up, and squeeze them once more at the top, then slowly lower your hips back down.
