Weight / Fat loss

Here's my ab fun session:
10 toe touch
10 v sits
10 garden variety sit ups
20 back ext (making sure to lock only on back- using your glutes is cheating!)
1 min plank
20 leg ups (plank position knee to chest with minimal hip raise)
10 press up half burpees
10 sprint starts counting 1234
20 back plank leg raises
20 ab cycles as slow as you can go
Repeat x2 or 3 1min rest between sets.
Try and do the whole thing 2ce a day.

Needs more back, but I tend to do quite alot of that elsewhere, but will probably rejig to incorporate.
