Core Challenge Workout – Day 1

Welcome and congratulations for taking up our January Challenge!

Today we have timed exercises so grab your iPhone or a watch or get close to the clock at the gym.

Here’s your Core Challenge Workout for today:

  • Plank
  • Bicycle Crunch
  • Reverse Crunch

Perform each exercise for 40 seconds with a 20 second rest in between.  (Note:  If you are unable to do the full 40 seconds, do what you can, take a break to regroup and continue until your timer beeps.  There is no failure here so do not get discouraged!)

Do the sequence 2 times through.

How To Do the Exercises


  1. Hold yourself in the “up” position of a pushup, hands under or slightly in front of your shoulders, fingers spread, apart, pointing forward (do NOT turn your hands toward each other or away from each other).
  2. Press your feet, knees and thighs together
  3.  Draw your shoulders down away from your ears and engage your shoulder blades so they are slightly pulling toward each other
  4. Lift your belly up nice and tight, pulling your belly button toward your spine
  5. Drop your tush a bit so it’s in NOT pointing in the air
  6. Keep your back straight – don’t drop your belly, tuck it up

Bicycle Crunch

  2. Place hands behind head

  4. Rotate your torso to the right so that your left elbow and right knee in the middle of your torso (this is the start position)
  5. Keep left leg straight out, about 18 inches off the ground
  6.  Keeping abs tight, rotate torso to the left so that the right elbow is now meeting the left knee in the middle of your torso and left leg is now extended
  7. Continue rotating so that opposite elbow and knee meets in the middle
  8. Make sure that your extended leg is as low to the ground as can possibly be

Reverse Crunch

  1. Lay on your back with your hands at your side. palms facing down
  2. Raise your knees and bend them at a 90 degree angle
  3. Keep your head and shoulders firmly on the ground
  4. Press your palms into the ground as you lift your hips and roll your knees toward your head
