Protein is an undeniably important nutrient if you want to get stronger – it helps muscles rebuild microtears in the tissue caused by training. But don’t let the hunt for gains detract you from other essential nutrients – particularly zinc. As well as supporting the immune system, it also plays an essential role in bone metabolism (to prevent osteoporosis) and mineralisation (creating hardness and strength in the bones), helping them to withstand lifting or pressing heavy weights.

This smoothie is the chocolate-coated way to pack in more zinc, thanks to cashews and cocoa. Serve up for a pre-workout breakfast or a sweet afternoon snack to settle cravings and your body’s needs. Protein shake, step aside.  

What? Allbirds Women’s Tree Dashers, £120

What is it? A technical running shoe made from natural materials that are engineered for enhanced performance.

The verdict: “The customer rating on these trainers is a 4.8 out of 5 stars and it’s easy to see why – I’m hard pressed to find a fault. I’m not one for flashy logos or colour, so I love their sleek, minimalist style – the tongueless-design and sock-like ankle makes them so smooth to slip on. An impressive breakdown of the materials is available online: the knitted covering is made from eucalyptus trees, the midsole is created from sugar cane, and the removable sockliner is made from castor bean, which emits less carbon than petroleum-based foam.

I’ve been wearing them for everything from HIIT and walks to runs and strength training for weeks now – and every time I’ve felt not only supported, but comfortable. There’s added cushioning along the heel to lock your foot into place and the midsole is engineered to cushion impact and return energy. 

Besides being a beautiful, functional shoe, the trainers are carbon neutral and their dual-density SweetFoam™ midsole is made with the world’s first carbon negative green EVA. If a sustainable sneaker can still be sexy and practical, I don’t know why all brands can’t do the same.”
