HOW TO DO IT: Start in a high plank. Push your hips back without arching your lower back until your knees flex to about 90 degrees. Pause for a beat, then explosively extend through your knees, ankles and hips while also pulling with your upper back as you lower into the bottom of a push-up. Keep your elbows tucked into your sides to protect your shoulders. Skip the push-up and just maintain a hold if you need it to be easier.
Borden is a fan of all types of glute bridges for activating your glutes, especially when you're on the road. "Traveling means sitting a lot," she says. "When we sit a lot, our hamstrings [and] hip flexors all shorten and tighten up." Over time, this can make it challenging for your glutes to engage the way they're supposed to, in the gym and in day-to-day life (this is also known as dead butt syndrome). Incorporating glute bridges in your routine can help combat this.
