Start on the floor on your hands and knees. Place your elbows directly under your shoulders. Step your feet back, one at a time. For more stability, bring your feet wider than hip-distance apart. Bring them closer for more of a challenge. Maintain a straight line from your heels through the top of your head, looking down at the floor. Do not look forward or up. Now hold. Start with 15 seconds. Work up to 2 minutes as you get stronger. Please remember to always warm up and cool down before and after exercising. Stay tuned for part 3 coming this week 💥 Did you try this exercise? Let us know in the comments how long you held the plank for👇 #TeamSpeedo #Speedo」3月26日 21時00分
