Exercise Is Medicine — And Strength Training Gives You the Most Bang for Your Buck

Most people still think of exercise as something you do to “stay healthy” or “look better.”

A major scientific review published in the Scandinavian Journal of Medicine & Science in Sports makes a much stronger claim: exercise should be treated as medicine.

The authors reviewed the evidence for using exercise as therapy in 26 different chronic diseases, including type 2 diabetes, heart disease, high blood pressure, depression, osteoarthritis, osteoporosis, and several neurological conditions. Their conclusion was clear: for many of these diseases, the evidence supporting exercise is as strong as (or stronger than) some commonly prescribed medications.

Why Strength Training Stands Out

As usual, aerobic exercise gets most of the attention. Walking and cardio have benefits, no question. But when you look at the bigger picture — metabolic health, muscle preservation, joint support, functional capacity, and long-term independence — strength training delivers the most bang for your buck.

Muscle is metabolically active tissue. It helps regulate blood sugar, supports your joints, protects against frailty, and keeps you capable as you age. Losing muscle is one of the biggest drivers of declining health and independence later in life. Strength training is the most direct way to fight that.

For busy adults in their 40s, 50s, and beyond, this matters even more. You don’t need long cardio sessions or complicated programs to get meaningful results. You need training that creates a real stimulus in a short amount of time — and that you can actually stick with.

What “Exercise as Medicine” Looks Like in Practice

The research makes an important point: effective exercise isn’t vague advice to “move more.” It requires enough effort to produce real physiological change, done consistently over time.

In practical terms, this means:

• Prioritizing strength training as the foundation

• Training hard enough to create adaptation

• Keeping sessions short and efficient so they fit real life

• Focusing on consistency instead of perfection

This is why brief, focused strength sessions work so well. They deliver a high return on the time invested without requiring hours in the gym. The goal isn’t to exhaust yourself. The goal is to create the adaptation your body needs and then recover.

The Bottom Line

Exercise is not just preventive. For many chronic conditions, it is an evidence-based therapy.

Among the different forms of exercise, strength training stands out as one of the highest-leverage options available — especially if your goal is to stay strong, capable, and independent for decades. And when you remove the factor of adverse side-effects of many medications, and their various interactions with each other, it's the smart financial choice as well.

You don’t need extreme programs or hours of cardio. You need an approach that is effective, efficient, and sustainable.
