It turns out, science backs this way of training, too, to an extent. Sports scientist and PT at Metrix, Toby Spooner, says this mix of exercises will “enhance overall fitness because it’s stimulating both cardiovascular and muscular systems”. So, it’s not just in my head that it’s working for me. Samantha Cubbins, lifting club manager at Gymshark says such a varied fitness program means different parts of the body are pushed. “Aerobic exercises improve heart health and lung capacity, while strength training boosts muscle mass and metabolism,” she says. “Flexibility exercises enhance range of motion and prevent injuries, and balance exercises help improve stability. High-intensity interval training (HIIT) burns fat and boosts endurance, while functional training mimics real-life movements to improve daily strength.” This all together will improve overall fitness, Cubbins says, as well as preventing boredom.
