“These days, I do a fair amount of Pilates and yoga to focus on the strength of my core. You don’t have to be a crazy cardio bunny to lower your body fat percentage (to get those abs to show)—bodyweight exercises can be really effective. Yoga and Pilates help me focus on overall strength, not just my core, and it helps make sure I work my back, too. Most people forget about that, but you need a strong back to help support a strong core.” —Dorothy Beal, @mileposts
Warm up and cool down for 5 to 10 minutes. Go for a brisk walk or jog, do jumping jacks, run in place, or jump rope at the start of your workouts. Moderate aerobic exercise will increase blood flow to your muscles, which reduces your risk of injuring yourself. When you finish working out, cool down for 5 to 10 minutes to help your muscles recover.
Begin in the basic plank position. Your torso will be in a straight line from head to toe and avoid any drooping or sagging of the hips or shoulders. Also, avoid arching your back, or hanging your head. Warm up by maintaining the plank for at least 60 seconds while maintaining control. If you start shaking or losing form, drop to your knees and rest a few seconds and continue until you've completed a full minute
Trainer tip: You know planks, right? It’s easy to go through the motions here. Don’t do it. “The key is to squeeze your entire body—quads, glutes, core, back, and fists—as tight as possible while taking diaphoretic breathes throughout the hold,” says Wealth. No matter how many times you’ve done it, this exercise is as difficult as you’re willing to make it.
