Core Burner

This is great to add in at the end of a workout or just on those days you may not have a lot of time.

* If you do this at the end of a workout, you shouldn't have to warmup. Although if you are doing this as a stand alone short workout, then you should warmup with dynamic stretching. Check out our dynamic warmup in earlier posts.

You will need a stopwatch or timer. You or your workout partner can time the holds.

* Hold a plank for as long as possible
* Rest the same time as the plank hold, then go right into plank

* Repeat the above 5 times each *

It would help to mark your times so you can see development in abdominal strength. Lapping with timer is your best bet.

Always remember that both rest and proper nutrition will be the deciding factor with your fitness improvements.
