Under Par X Onyx

Our Collaboration

Elite golf performance isn’t just about technique - it’s about how well your body supports your swing, your practice, and your ability to perform under pressure. That’s why Under Par Golf has partnered with Onyx Performance to deliver a fully integrated golf and fitness solution, designed to help golfers move better, swing faster, stay injury free, and play better golf for longer.

This collaboration bridges the gap between coaching and physical performance, ensuring everything you work on technically is supported by your body.

Why Golf & Fitness Must Work Together

Golf isn’t just a skill sport — it’s an athletic movement sport. The modern game demands strength, mobility, balance, and control. When golf coaching and fitness training work together, performance improves faster, injuries decrease, and consistency becomes easier to achieve.

Many golfers hit performance plateaus not because of poor coaching, but because their bodies cannot consistently produce the movements required.

Common issues we see:

  • Limited mobility restricting swing positions

  • Poor stability affecting strike and consistency

  • Lack of power leading to reduced distance

  • Injuries and niggles limiting practice and play

By combining world class golf coaching with bespoke performance training, we address the root cause - not just the symptom.
