First off, apologies, it's pretty manic at the moment juggling a few issues so I'm not getting on here as much as I'd like. Will do better 🙄 Anyway, I did this circuit yesterday and it kicked my butt... The idea is to work through the 3 exercises with little to no rest. I'd strongly suggesting starting at a low rep range if any of these seem hard. I started with 15 reps of : Bag to overhead Bag split jumps Bag press ups Then I did 14 of each, 13 etc all the way down to 1. I aimed to get it done in under 30 mins and just about managed it. Give it a try and see how you get on 👌
