Side planks strengthen the entire side of your body for better side-to-side and rotational movement.

Image Credit: Morit Summers/LIVESTRONG.com Creative This 31-day body-weight workout challenge will inspire you to move more, no matter your starting point. Get all the details on the challenge here. When you’re getting ready for a strength-training session, think of yourself as a house. You need a solid foundation of strength to build on. That’s why it’s important to build core strength. Your core stabilizes your whole body and initiates pretty much every movement.

 Morit Summers, CPT, creator of Brooklyn-based training studio Form Fitness and host of our "New Year, Do You" Challenge, designed the following workout to activate and strengthen your body's powerhouse: your core (aka your abs, back and glutes). Strengthening these muscles ultimately helps you generate more power in your strength-training sessions.

 If you're doing the challenge, follow the weekly rep scheme below. If you're doing this workout on your own, increase or decrease the reps and sets based on your fitness level. You should be able to do all the reps with good form, but the last two should feel challenging.

 In between sets and exercises, rest for 20 to 40 seconds. You won't feel fully rested (like you were before your workout) but you should feel ready to tackle the next set.

 1. Side Plank (shown on right)      
        Activity
       
        Body-Weight Workout
      
        Region
       
        Core

Lie on your side with your legs and feet stacked on top of each other, just like Summers (right). Prop yourself up on your forearm. Keeping your knees straight, engage your abs and lift your hips off the ground, balancing on your forearm and bottom foot. Place your other hand on your hip or extend it up toward the ceiling. Hold for the given amount of time, then slowly lower back down. Repeat on the other side.

  Show Instructions
  Modifications and Variations To make this move a little easier, drop to your knees while you hold a side plank (shown on the left).
  1. Crunch (shown on left)
    Activity

        Body-Weight Workout
    
        Region
    
        Core
    

Lie on your back with your knees bent and your feet flat on the floor (shown on the left). Bring your hands behind your head so your elbows flare out to the sides. Your hands can overlap and rest on your head, but they should not tug on your neck. Exhale, contract your abs and lift your head and shoulder blades off the ground. Your neck can curl slightly, but it shouldn’t strain toward your chest. Inhale as you lower back down so your head is hovering just off the ground and repeat.

  Show Instructions
  Modifications and Variations For more of a challenge, hold your knees at a 90-degree angle so your shins are parallel to the floor as you crunch (shown on the right).
  1. Bird Dog (shown on left)
    Activity

        Body-Weight Workout
    
        Region
    
        Core
    

As Delgado-Lugo demonstrates on the left, start on your hands and knees with your hands directly in line with your shoulders and your knees in line with your hips. On an exhale, reach your right arm straight out in front of you until your upper arm is in line with your ear. Simultaneously reach your left leg straight behind you, fully extending your knee. Pause here for a moment before reversing the motion, crunching your knee into your elbow to complete one rep. Finish all your reps on one side before switching.

  Show Instructions
  Modifications and Variations For an added challenge for the bird dog, lift your knees off the ground and hover there as you move one limb at a time, tapping either your hand or foot a few inches behind or in front of you (shown on the right).
  1. Dolphin Plank (shown on right)
    Activity

        Body-Weight Workout
    
        Region
    
        Core
    

Start in a forearm plank, balancing on your forearms and toes and maintaining a straight line from head to hips to heels (shown on right). Hinge at your hips as you raise them up toward the ceiling, drawing in your bellybutton to protect your lower back. With control, lower back down into a forearm plank and repeat.

  Show Instructions
  Modifications and Variations You can also perform the dolphin plank from a high plank, balancing on your hands instead of your forearms (shown on the left).
