FAQs

  • Is Horseback on Chair suitable for beginners?

    No. Horseback requires advanced balance and core control. Building a strong seated posture and confident chair balance must come first.

  • What muscles does Horseback on Chair work?

    The deep abdominals and hip flexors hold the balance. The inner thighs assist in the straddle position and the shoulder stabilisers support any arm work added to the exercise.

  • What is Horseback on Chair good for?

    It is exceptional for core endurance, seated balance, and the body awareness needed to maintain upright control without external support — one of the most concentrated core challenges on the chair.
