The glute bridge is one of the most commonly prescribed rehab based exercises for posterior chain and specifically glute recruitment. However it could be cued more appropriately to allow for down regulation of the hamstrings.
Drive pressure through BALLS OF FEET (not the heel). Too often pressure through the heel elicits increased hamstring recruitment and under utilisation of the glute.
Lightly flicker the glutes. With a defined focus on glute tissue we can elicit a more localised recruitment
Maintain neutral spine- this allows an even amount of loading through the spine and encourages spinal stiffness.
