This 12 minute abs ladder workout is going to have your abs on fire by the end!
4 exercises repeated MANY times - we start with 10 reps of each, then 9, then 8 and so on and so on until we have completed 1 rep of each.
If you dont manage to get to 1 rep and step off the ladder entirely, dont panic! It doesn't mean you have failed, you can revisit this workout at a later date and see whether you can get a little further.
Have fun!
