Scaling:
Double unders – if you can’t confidently string together sets of 10+, reduce the volume (no fewer than 10-8-6-4-2), or do triple the number of single skips

Top tip:
Double unders are one of the most frustrating movements to learn but, once you get them, they are super satisfying and give a brilliant cardio and shoulder blast! Take time learning and try not to get frustrated… it’ll be worth it
If you’re confident with double unders, get them squared away quickly and move steadily throguh the sit ups, without breaking if possible.
