The back extension exercise is an effective way to increase the strength and tone of your spinal musculature. With a slight modification, you can also use this exercise to target your hips, giving your glutes and hamstrings a solid workout. The result is an exercise that builds a solid, functional posterior chain.

Difficulty: Moderately Easy
Instructions
  1. Step 1

    Find a back hyperextension or glute-ham raise apparatus in your gym. These put your body into the correct position for working out your back.

  2. Step 2

    Hook your legs into the machine's padded ankle locks. Then, rest your lower abs on its hip pads.

  3. Step 3

    Curl your head toward your chest, as if you were doing a crunch.

  4. Step 4

    Round your back slowly, and lower your upper body toward the ground.

  5. Step 5

    Pause at the bottom of your range of motion, then begin the extension by contracting the muscles in your hips.

  6. Step 6

    Lift your shoulders and head toward the ceiling as you rise. You should feel the muscles around your spine working to lift and extend your upper body.

  7. Step 7

    Repeat the exercise 5 to 10 times for one set. Do three sets.

Tips & Warnings
  • Hold a weightlifting plate against your chest to increase the core extension's intensity.
  • Start the extension with your hips, then finish it with the muscles of your back.
  • Finish the core extension with your back in a neutral spinal position.
  • Don't drop down from the extended position too quickly. Going too fast can cause serious knee or back injuries.
