With the menopause comes re-distribution of fat, with more around the waist and hips: is this more a male fat-distribution? And as we age we lose muscle tone, about which we can do a little; and lose elasticity in connective tissue, about which we can do nothing. And the age at which this happens varies a lot. Having taught Pilates for many years, it was evident in front of my eyes as I saw my class participants, however skinny, developing a spare tyre, which may be very small, but there it was. And of course it hit me hard. So it doesn't matter how slim you are, or how much Pilates you do - my daily dose is 45 minutes, plus at least an hour of cardiovascular, and an alkaline (vegetarian) for many years, I can pull in my abdominals to flatten them, but plenty of fat particularly on my lower back, waist thickened, and well as loads of wobbly bits: all that loss of elasticity. Sigh...
