Do:

• Lie on back with hips and knees bent 90 degrees
• Hold fists between knees, squeezing them with knees
• Separate ankles outward by rotating hips while maintaining pressure with knees on fists
• Repeat rotations for 30 seconds [for a challenge, hold at end for additional 30 seconds]
• Perform drill two times every day

Don’t:

• Let up on pressure between knees
• Perform drill for less than 30 seconds or for more than one minute
• Bounce when performing
• Skip stretching sessions. Hip flexibility can improve in just two to three weeks with constant work
• Ignore stretching. Lack of hip flexibility forces overcompensation in spine rotation during swing, which can lead to back injuries
