Quick Strength for Runners Exercise: Knee Crunches

Quick Strength for Runners offers a smart, fast-paced strength training program for runners who want to run faster and with fewer injuries. In under an hour a week, runners will strengthen their core and key running muscles to build a better runner’s body.

MUSCLE TARGETS: Abs (rectus), hip flexors, obliques

EQUIPMENT: None

FORM

  • Sit on your exercise mat. Stretch your legs out in front of you, with your knees fully extended. Keep your arms at your sides, palms facing downward on the floor.
  • Bring your knees toward your chest, then extend your legs again, keeping your feet off the floor.

 

TIP: If you are having trouble keeping in place on the floor, wedge your hands under your backside to keep from sliding around. Eventually, you should be able to fold your arms across your chest, using only core strength to hold your body steady.

REP: Return to the starting position. This constitutes 1 rep.

# REPS: 10-50

ADVANCED FORMS

  • Keep your upper body off the ground while performing this exercise. This causes you to balance on your backside, which engages your lower back and core even more.
  • Hold your body in the crunched position for a count of 5 before returning back to the floor.
