Best came up with her mood matching plan mainly out of frustration. “In fitness products for women, the language and focus is so often on aesthetics. Workouts and programmes are marketed with phrases like ‘booty builder’ or ‘fat blast’,” she says. “The women I coach are so busy, juggling big jobs, full social lives and sometimes family life too, so I wanted to give them the reminder to pause before they start exercising to ask themselves ‘How do I actually feel right now?’ in order to support their mental wellbeing as much as their physical bodies.”

While the conversation around moving to feel better is getting louder, we still don’t tend focus on the fact that different forms of exercise impact our bodies, minds, hormones, nervous system and mood differently.

For example, we know that high-intensity exercise dramatically increases cortisol in the body – that’s useful if you want to feel more alert and improve your fitness, but “if you’re already feeling stressed, an intense HIIT session that pushes your cortisol even higher isn’t the best idea,” says Best. Instead, she saves these intense sessions for the days you’re feeling energised, and recommends slower, strengthening, stretchy sessions on days your cortisol is already spiking.

“If you’re feeling angry, I suggest a boxing workout. It gives the therapeutic benefits of concentrating on skill as you learn the specific combinations to help channel and process that emotion,” Best adds.
