The first column in this Fit for Life series was Squaring the Geriatric Curve. As you get into your 50s your physical capabilities naturally and inevitably start to decline. You can’t stop this; however, you can control the rates of decline of your different physiological systems. Squaring the geriatric curve means slowing the rates of decline as much as you can. Staying as fit as possible — slowing your personal geriatric curve — rests on four pillars: 1. Consistency 2. Intensity 3. Recovery 4. Enjoyment I’ll explain each of these in this and the three succeeding columns, starting with Consistency.
