Most people think shoes hold up their arch. But bending your big toe back tightens the plantar fascia and winches your arch up (the windlass mechanism), stiffening your foot to push off. Action Tip: Barefoot today, keep the ball of your foot down and lift your big toe 10 times per foot. That's "The Arch Winch". What's your current foot habit?

Most people blame willpower when they overeat. But if protein is too low as a share of calories, your appetite stays on until you hit that protein target, so you keep eating. Action Tip: Build today's main meal around a palm of protein first, then add the rest. That's "The Protein Anchor". What's your current protein habit?

Most people think crunches burn belly fat. But you can't choose where fat comes off: training a muscle builds that muscle, while fat comes off your whole body via a calorie deficit. Action Tip: Swap 10 minutes of crunches for squats, rows and push-ups. That's "The Big-Three Swap". What's your current belly-fat approach? Vote below, then comment: which area do you most want to change?

Most people think iron-rich plants are enough. But plant (non-haem) iron is absorbed less well than iron from meat, and tea with meals cuts it further. Vitamin C alongside boosts uptake. Action Tip: Pair beans, lentils or chickpeas with peppers or citrus. Have tea between meals. That's "The Iron Escort". What's your current iron habit? Vote below, then comment: what's your go-to iron-rich meal?

Most people judge a session by how much they sweat. But sweat is your cooling system, not a fat meter: it rises with heat and humidity. Any weight lost is water, back once you drink. Action Tip: Judge today's session by your log (reps or load), not your T-shirt. That's "The Dry Shirt Test". What's your current workout yardstick? Vote below, then comment: what tells you a session went well?
