When conducting exercises in water, why might participants cross their arms over their chest?

Crossing arms over the chest during aquatic exercises is primarily done to maintain a neutral arm position. This position allows participants to focus on their body's alignment and stability without having to manage the movement of their arms. By placing their arms across the chest, participants can also reduce any potential distractions that might arise from arm movements, thus allowing for better concentration on their lower body movements or core engagement.

This arm position can be particularly useful during certain exercises where balance or stability is key. It helps to distribute the body's weight evenly and creates a more stable base, enabling participants to perform movements with better control and reducing the risk of improper form. Additionally, with arms crossed, participants might find it easier to connect with their core muscles, as they can channel their energy without being offset by arm movement.
