Had an NHS health check today as I am over 50 years old, BMI 21.9 so fine, cholesterol and blood pressure all good but my waist is 81cm which is borderline increased risk of heart problems. I already do 4 classes at the gym each week including 2 spin classes where I leave dripping in sweat, weight is 9 stone, how do I lose inches off my waist? I’m pescatarian, barely drink, don’t smoke. The health professional didn’t seem concerned but I would like to reduce my waist size, I have always had a thick waist even when I was very underweight at 18. Any suggestions apart from sit ups etc which I already do sporadically.
