Fitness Challenge Day 23

The Exercise:  Prone Jacknife

Variation 1
Variation 2
  

Okay, we are revisiting the jacknife for our core day.  For a refresher go back to our last jacknife workout on Day 9.  We started with a jacknife like the one pictured above in Variation 1.  For those of you looking for a bit more challenge, try variation 2 this time around, these are more difficult as your weight comes more into your arms and they really take some core strength as well as arm and shoulder strength and stablility.  Remember to keep your back as flat as possible in both variations and work from your core, not your lower back.

The Challenge:

Last time our goal was 2 sets of 10 for the uninitiated or 3 sets of 15-20 for your fitness-oholics.

Today lets try for 3 sets of 12 for the newbies with variation 1.

For our hard core cores out there try for 3 sets of 15 using variation 2.  

Don't forget to warm up first! 

Now, grab that ball and have fun!
