It’s simple; if you want to become as strong as possible, you must have a strong trunk. Without the ability to create a strong brace, you will miss lifts or experience a lower back injury that forces you to take time off. If you have a weak trunk, it is only a matter of time before something goes wrong.
Implementing bodyweight exercises allows you to increase your strength, size, athleticism, and mobility. Movements such as pull-ups, sit-ups, push-ups, dips, air squats, Hindu squats, and burpees are some of the oldest exercises we have used to increase physical fitness.
