TRX Hip Bridge with Alternating Knees is a challenging lower-body and core stability exercise performed using suspension straps. From a lying position with your heels placed in the TRX handles, you lift your hips into a bridge and then alternately bring one knee toward the chest while maintaining hip elevation. This dynamic movement targets the glutes, hamstrings, and core, while also enhancing balance, pelvic stability, and posterior chain control. Ideal for improving unilateral strength, hip mobility, and core engagement in functional training routines.
