Which movement is suggested to help with glute engagement while performing calf raises?

The suggestion to pull in the glutes while performing calf raises is based on the importance of engaging the glute muscles to enhance overall stability and strength during the exercise. Engaging the glutes can help to stabilize the pelvis and lower body, allowing for a more controlled and effective calf raise. When the glutes are activated, it encourages proper alignment and engages additional muscle groups, leading to improved performance and overall effectiveness of the exercise.

In contrast, the other options do not directly contribute to glute engagement during calf raises. Jumping jacks focus on cardiovascular endurance and do not target glute activation. Single leg curls primarily target the hamstrings rather than the glutes. Wide steps across the pool may improve lateral movement and dynamic stability but do not specifically enhance glute engagement during calf raises.
