Butterfly stroke
The butterfly stroke evolved from the breaststroke in the 1930s when swimmers began bringing their arms forward over the water instead of at their sides. It was refined throughout the 1930s and officially recognized as its own stroke at the 1952 Olympics. Key elements of the butterfly include a Y-shaped arm pull followed by straight back movement, synchronized up-and-down leg kicks on the sides, and breathing every other stroke or using a two-up-one-down breathing pattern. Proper body movement in a wave-like fashion controlled by the core is important for efficiency.
Swimming
Swimming involves moving through water using the arms and legs. There are several competitive swimming strokes including freestyle, backstroke, breaststroke, butterfly, and individual medley. Mastering basic swimming skills like breathing, gliding, coordination, and diving are important before learning strokes. The breaststroke involves pulling arms in and a frog kick while the butterfly requires precise timing of arm and leg movements together. Freestyle uses alternating arms with a flutter kick. Proper techniques for backstroke, breaststroke, butterfly, and freestyle are described.

3) The headstand balances the body vertically on the forehead and hands in a triangular position with the legs lifted overhead.
4) The handstand maintains an inverted vertical position supported by straight arms while lifting one leg at a time to join overhead.

How to Swim: Butterfly
- 2. Body Position: Body starts parallel to the water: Prone Arms are pointed forward: Wider than shoulder width Head should be facing downwards: looking at the bottom When you initiate the stroke: the body should bend and flex like a dolphin ~ in a ‘S’ shape
- 3. Pull: Similar to doing 2 Freestyle Pulls Both hands extend in front of you when you enter the water – they have to enter simultaneously When pulling: Bend the elbow so fingers point towards the pool bottom, arm angle should be about 150 degrees Position remains the same until past the hips, where you straighten out the arms * ‘S’ Shape of the arms for more pulling as it increases amount of water pulled just like in Front - crawl [diagram]
- 4. Recovery: Thumbs face downward Keep your thumbs [thus your arms] just above the surface of the water – this will decrease the rate of fatigue All this will require a full extension of the arms If you need to breath; do it during this period: Arch your body slightly up so your chin comes out of the water ~ remember to duck your head back in the water before your hands come over your head into the pool [try to stay as low as possible]
- 5. Kicking: Kicking comes from the core of the body: the center Butterfly kick is done as 1 leg: keep the legs close to each other 1st Step: Press the body down [the chest] onto the water 2nd Step: Allow the body to follow through: Like a whip that extends all the way to the end of the foot [the knees can bend slightly – do not overdo it] 3rd Step: Timing: 2 Kicks done per ‘cycle’ Kick 1 – Hand first enters the water [gentle kick], Kick 2 – During the midsection of the hands [strong kick]
