We don’t know too many people who get excited about doing planks. Generally, you stare down your timer as the minute (or more) runs down. And while we’re being candid, let’s just come out and say it: Planks destroy your abs. For a pretty basic isometric exercise, planks strengthen your entire body—they make your core pop, strengthen your lower back, and build your shoulders.
Better yet, you don’t need any equipment, and you can amp-up the intensity by widening your stance and bracing yourself with your hands instead of your forearms and elbows. See for yourself. Check out what Keith Scott, A.T.C., C.S.C.S., a strength coach in Medford, N.J., recommends for conquering the plank before you attempt any heavy-weight exercise. You’ll be better for it, guaranteed.
Get into pushup position on the floor
Now bend your elbows 90° and rest your weight on your forearms. Your elbows should be directly beneath your shoulders, and your body should form a straight line from your head to your feet. Hold the position for as long as you can. Your goal should be to hold it for two minutes.
"The plank helps develop strength in the core, shoulders, arms, and glutes," says Scott, making it a great prerequisite for lifting heavy weights or playing intense sports. Even though you aren't moving or lifting weight, you have to constantly squeeze your abs to hold the position—most people can't last 30 seconds on their first attempt.
Ways to improve your plank time
The longer you can hold the plank, the more resilient your lower back will be to injury, and the better your abs will look once you burn the fat off them. Follow these tips for longer plank times.
- Practice: Perform planks several times each day, trying to hold the position a little longer each time.
- Use bodyweight exercises: Pushups and pullups will improve your core strength.
- Squat and deadlift: Guys who are strong in these specific lifts find planks are no problem.
If you don't have the core strength yet to do a regular plank, you can build up to it by doing a bent-knee plank. If you can hold a plank for more than two minutes with ease, you can move on to these tougher variations.
- Lift one leg up. By simply raising one leg in the air, you dramatically increase the demand on your core to fight your body's natural urge to rotate.
- Lift one arm up. Again, your body will want to fall to one side. Don't let it.
- Use a Swiss ball. Rest your forearms on the ball and you'll have to stabilize your body and stop the ball from rolling out from under you.
