Take that gym backpack that isn't getting much use right now and and stuff it with some household goods for weighted strengthening exercises, said Chloe Trigg, head trainer of strength & conditioning at Blok. We love the Sweaty Betty All Sport Backpack (£85) in black.
"Add as much weight to your backpack to suit your ability, whether it be some cans of beans, a couple of bottles of water, or some books," said Chloe. "Then tackle some simple bodyweight movements like air squats, planks, and push-ups. The added weight will deliver extra stress on your muscles, helping to strengthen and build them up. As you get stronger, the more weight you can add — homemade progressive overload."
