The best way to get a strong, stable core isn’t doing hundreds of neck-crunching sit-ups. Holding the body in a plank position strengthens the abs, back, arms, and glutes. Remember to keep the body in a straight line from head to toes to get the most out of this static exercise move.
Master the plank before attempting push-ups (which begin and end in the same position).
Loose and Limber:
Begin any workout with a dynamic warm-up to prevent injury.
