Dolphin plank position
Start in a plank position, with your forearms and palms on the mat and your shoulders aligned just above your elbows. Your body should form a straight line, starting at your feet and ending at your head.
Lift your hips upward while keeping your core muscles contracted and your legs straight. To complete one repetition, pause and return to the starting position (always with control).
Do 20 repetitions.
