Do These Three Things to Transform Your Body at Any Age

A leading exercise scientist says there are just three things you need to do to build a stronger, healthier body — and they work at any age. Dr. Brad Schoenfeld is a professor at Lehman College in New York and has written more than 400 research papers on strength training. He recently shared his simple plan for getting fit, and the good news is that it does not require fancy equipment or hours in the gym.

Dr. Schoenfeld says the most important key to a good strength training plan is consistency. You do not need to work out every single day or follow a very strict diet. He says that just two 20- to 30-minute workouts each week can bring 'huge improvements' to most people's health and fitness. That adds up to less than one percent of your entire week.

You will not end up looking like a professional bodybuilder with this routine. But you will build a body that looks good, feels strong, and can handle the challenges of daily life. On the inside, your heart will get healthier and your risk of serious long-term diseases will drop significantly.

The second part of Dr. Schoenfeld's plan is to work every major muscle group during each workout. This means doing exercises that target your chest, back, shoulders, arms, legs, and core. By hitting all of these areas twice a week, you make sure no part of your body gets left behind.

The third key is challenge. Your body only changes and grows stronger when it is pushed to work hard. If an exercise feels too easy, your body has no reason to adapt and improve. As Dr. Schoenfeld explains, the last few repetitions of each set should feel difficult to complete.

However, he also gives an important warning for beginners. 'Don't push yourself really hard during the first few sessions because you will get really sore,' he says. Instead, use your first few workouts to learn the correct form for each exercise with lighter weights. Within a couple of sessions, your body will adjust and you will be ready to push progressively harder.

The results of strength training can be amazing, even for very old people. In 1990, researchers studied 10 frail people who were 90 years old or older. After eight weeks of leg exercises on a machine, their strength, walking speed, and mobility had all improved greatly. Some no longer needed walking sticks, and one person could stand up from a chair on their own.

This study shows that everyone has the ability to exercise in some form. Even simple moves like sitting down in a chair and standing back up can count as a strength exercise. If you make it harder over time — like by using a lower seat or dropping your arm support — your body will keep responding. The three keys stay the same: be consistent, challenge yourself, and work your whole body.
