Get creative with your props and grab a large cast iron pot from your kitchen, "preferably a large with handles on both sides," said Katie Anderson, head of training at Fly Ldn. This Le Creuset Cast-Iron Round Casserole Dish (£99), is a perfect example.
"Fill the pot with tins or books to a weight you feel is challenging to lift," explained Katie. "This is to replace holding a dumbbell or kettlebell that you would normally find in the gym. You can hold the weight as a cradle to the chest when you're doing leg exercises, and also for two-handed bicep curls and core work. For exercises on how to use this at home, check into Fly Ldn IGTV in the next few weeks for a tutorial."
