5 Equipment-Free Moves for Full-Body Muscle Strengthening.

This five-move bodyweight workout can help improve posture and sculpt your back and core muscles without the need for pull-ups or heavy weights. The exercises target various muscles in your back, including your lats, erector spinae, rhomboids, trapezius, rear deltoids, and core muscles. Strong back and core muscles are responsible for good posture, protecting your lower back from injury, supporting trunk movement, and improving overall strength across your upper body.
