When performing single leg glute activation movements, one foot may be placed on a stretching block. This elevates you and requires core engagement for stabilization that is useful in cycling. Get it by positioning a block on the floor and standing on one leg with one of the feet on the block and performing the single leg hip thrust by bending at the hip and elevating up using the glute. This assists in keeping the hips level and square, a position that is optimal in cycling.
