Simple exercises like Side Planks are excellent to expose weak points in our postures. You feel them right away. I recently assessed someone with low back pain who held for 15s on one side but only 5 on the other. Work your way up to 1 min each to balance your posture.

Start with your knees bent if you struggled with the full Side Plank. This variation will strengthen your foundations until you can support your whole body.

Add Reverse Flys once you can hold for a minute. You’ll involve more muscles and increase the load on your core and upper back muscles.
