Start in a high plank with your hands shoulder-width apart, palms flat on the floor, and feet hip-width apart. Your head-to-heels line should be straight. Think about sucking your belly button into your spine to straighten your back.
Engage your core, elevate your hips, and stay still. Try downward dog. Lift your right hand and tap your left foot as your hips rise. Keep your back straight. Slowly return to high plank. Switch sides. One rep.
Day 1 I started day one with zest, pulling off the bandaid and doing all 90 in one go. Around midway, my shoulders were aching from this strategy. Plank toe taps engage your upper and lower body, unlike a high plank for 60 seconds.
After 90 reps, my core was exhausted. As I got fatigued, I was pushing from my shoulders, not my hips. I slowed down and did three sets of 30 reps for the rest of the week because this exercise should move the lower body.
Day 4 Plank toe taps, like the yoga sessions I skip mid-marathon training, helped me stretch before running. The 90 toe taps a day helped stretch my tight hamstrings and lower back as a runner.
