Thankfully, there’s an ongoing awareness that aging well requires being physically fit. But many people are unsure of what being physically fit actually means. Does being fit mean that you can run a mile in 8 minutes? Or does it mean that you can touch your toes or do 25 push-ups in one minute? There are five prime components to being physically fit and regardless of age, extending oneself in these five key areas of health are critical to healthy aging. There are additional areas not traditionally considered part of physical fitness like balance training and mental training but will be considered in upcoming articles.

Keep in mind that aging well is an ongoing process so although we may get specific testing data on where we should be performing in each fitness category based on gender and age, truly aging well requires expending energy in these five key areas over a lifetime.

Cardiovascular Fitness
Minimum 20 -30 minutes 4 days a week
Heart rate at minimum of 70 %. Formula is 220 minus age multiplied by .70 = HR minimum. Example for a 71 year old minimum at 70% is 104 beats per minute while exercising the heart. *Those on beta blockers will not use this formula and should consult their doctor on exertion levels.
Exercise must use leg muscles and be a continuous motion to be considered cardiovascular in nature. Ex. walking, biking, stair climbing, jogging, elliptical trainer, cross country skiing.

Muscular Strength
How much upper body can lift for one repetition. How much lower body can lift for one repetition. * Should not try this one rep maximum especially if you have not been training. There are rules that apply to this depending on the age of the person.

Muscular Endurance
How many repetitions upper body can lift in one minute. How many repetitions lower body can lift in one minute.

Flexibility
The range of motion in such areas as the hamstrings ( back of legs), upper and lower back areas, shoulders, hips, neck, and quadriceps ( front of thigh.)

Body Composition
Being at a weight that is comfortable for the individual given his lifestyle needs. It includes being at a weight that does not contribute to elevated blood sugars, lack of energy, cardiovascular risks, osteoarthritis, and other increased body fat health issues.
Includes being at a body fat that is considered within normal range. This varies but typically men should look at a range from 10-18% depending on age and lifestyle needs and women at 18-26%.
Regardless of age, extending ourselves in these five key health areas, studies have shown, reduce premature aging and are vital for aging well.
