Step 1: After taking your final breath on the surface, remove your snorkel and perform an equalization.
Step 2: Next, put both arms out in front of you and dive forward with your arms leading your upper body, bending at your hips to create a right angle.
Step 3: Then raise one or both of your legs out of the water vertically, making your body straight again. The momentum of your legs, above your right-angled body, will push you under the water without having to make any additional effort.
Step 4: Pull your arms and bring your one hand to your nose to equalize, and then keep it there to continue equalizing.
Step 5: Once you have pulled your arms into you and you have equalized, start finning.
