Mobility and fitness begin to decline with age, leading to loss of strength and stability. Researchers now believe any kind of exercise is beneficial, even in later years.

What is physical fitness? It’s defined as a state of health necessary to exercise and complete daily activities without getting overly fatigued. Good fitness requires strong muscles, flexibility, and endurance.

To stay fit, you need to improve your aerobic fitness and strength. Having strong core muscles—the muscles of the abdomen, back, and pelvis—help you stay upright and make it easier for you to be physically active. Core exercises for seniors strengthen these muscles without causing excess stress. Programs such as Pilates, tai chi, and stability ball training work core muscles in a safe, effective way. Specific abdominal exercises such as crunches and planks create a flatter, more toned stomach.

Pilates is a workout program that specifically targets core muscles. Exercises can be done using special equipment, or with the body’s own weight as resistance. Pilates strengthens the abdominal muscles and improves overall strength and flexibility. It also incorporates breathing techniques. Signature Pilates exercises include “The Hundred,” which involves lying on the back, lifting the legs, and pressing down with straight arms for a count of 100.

Diet is another important component to accompany mobility and fitness. To perform at your best physically, you need to eat a balanced diet, complete with fruits, vegetables, whole grains, low-fat dairy, and lean protein. People seeking to lose weight may try one or more different diet plans, from Weight Watchers to vegetarian.
