How do I calculate the calories burnt by planking, based on the time and weight?
How do I know if I am doing a good plank exercise?
A good plank exercise generally involves keeping your body in a straight line from your head to your heels, engaging your core muscles, and avoiding arching or sagging in your back. You can also focus on breathing evenly and holding the position for as long as possible without compromising your form.
