Tom thinks everyone should strength train. Here's why:
Increases metabolism/muscle mass
Strength training builds muscle. I know that's probably the most obvious benefit, but it’s extremely important. As we age, we lose about a pound of muscle every year after the age of twenty. Even people who exercise regularly, but neglect strength training will still lose ½ a pound of muscle a year. This causes us to get weak and makes us more vulnerable to fat gain as we get older because the metabolism is slowing down. Check out people who eat whatever they want and not gain anything, but as they approach 30-40 their metabolism has slowed and they are starting to gain weight. Strength training is the only way to maintain or add muscle mass as we age, keeping our metabolism running high.
Improves Bone Mineral Density
Not only does strength training stimulate muscle growth; it also stimulates the growth of bone tissue. This is one of the main reasons why women should do some form of strength training, as 1 in 2 women or there about now develop osteoporosis.
Improves Joint Strength and Stability
Increasing the strength of muscles, also greatly enhances the strength and stability of the joints these muscles surround. This is extremely beneficial to prevent injuries as we get older.
Decreases Arthritis
Strength training improves our bodies control of our joints, which decreases the stress put on them in day-to-day activities. This helps reduce the chance of our joints degenerating.
Improves Vitality and Quality of Life
The condition of our muscles is responsible for our ability to perform everyday activities. Muscles are like an engine, if they are well looked after, you can drive it regularly without fear of it breaking down.
Increases Fat Loss
Muscle is metabolically active, meaning it burns calories. Every extra pound of muscle we add burns approximately an extra 50-100 calories a day. Therefore, the more muscle we have the more calories we burn while we are sleeping, doing daily activities and through exercise. For example, the metabolism can be like a car, the more muscle you have, the larger the engine and the more calories you burn, much like the way a V8 chews through fuel.
Decreases Blood Pressure
Recent studies have shown that strength training can help reduce blood pressure. Therefore there is a less chance of developing heart disease. If our muscles are stronger, this places less stress on our cardiovascular system while performing day to day activities.

Don't be afraid to lift weights, it’s good for you. You don’t have the hormones men do to build large, bulky muscles, so don't be shy. You will only be able to replace the muscle you had lost through the aging process and at most maybe gain a few more pounds, but that’s it. Pictures you see of women looking like men with massive muscles are due to them injecting male hormones in them – that won't happen to you.

Strength training prevents our bodies from deteriorating enabling us to live and enjoy more of life as we age.
