Mistake two: locking out your joints
Locking out your joints means fully extending them to the point where they become full extended or even hyperextended. This can put excess strain on your joint structure and connective tissues, leading to injury. To avoid this mistake, focus on maintaining a slight bend in your joints throughout your strength training exercises. By doing so, you will engage your muscles more effectively and reduce the strain (and reduce the aging process) on your joints.
When performing exercises such as squats, and push-ups (even wall push-ups), always keep a slight bend in your knees and elbows. This will ensure that your muscles are doing the work rather than your joints. Additionally, focus on engaging the muscles around your joints will provide more long-lasting stability and support.
