STRENGTH & PERFORMANCE
The real reason strength training should be part of your fitness routine — no matter your age, goal, or experience level
CrossFit Una Stamus · June 2026 · 5 min read
When most people think about strength training, they picture bodybuilders, heavy barbells, and a gym full of people grunting under enormous amounts of weight.
So they skip it. They stick to cardio. They tell themselves lifting isn't really for them — that it's too complicated, too risky, or just not what they need.
Here's the problem: that decision is quietly working against them. Strength training isn't just for athletes or people chasing a certain physique. It's one of the most important things any adult can do for their long-term health — and one of the most underutilized tools in everyday fitness.
Let's break down why.
Strength training does far more than build muscle
Yes, lifting builds muscle. But the benefits extend well beyond how you look in the mirror. Done consistently, strength training:
- Increases your metabolism — muscle tissue burns more calories at rest than fat, meaning the more muscle you carry, the more efficient your body becomes at managing weight
- Strengthens your bones — resistance training increases bone density, which becomes increasingly important as we age and the risk of osteoporosis grows
- Improves joint health — stronger muscles support and protect your joints, reducing the risk of injury both in and out of the gym
- Boosts mental health — research consistently links strength training to reduced anxiety, better sleep, and improved mood
- Enhances everyday function — carrying groceries, picking up kids, climbing stairs — everything gets easier when you're stronger
In other words, strength training isn't just a fitness tool. It's a quality-of-life investment.
Cardio alone isn't enough
There's nothing wrong with cardio. Running, cycling, and rowing are all valuable. But if cardio is the only thing in your routine, you're leaving a lot on the table.
Here's why: cardio improves your cardiovascular system, but it doesn't do much to build or preserve muscle mass. And muscle mass matters — especially as you get older. Starting in your 30s, adults lose roughly 3–5% of muscle mass per decade without deliberate resistance training to offset it. That loss accelerates with age and contributes to fatigue, slower metabolism, reduced mobility, and a higher risk of injury.
Pairing strength training with cardio doesn't just make you fitter. It makes the cardio more effective, keeps your body resilient, and creates a foundation of health that lasts.
You don't have to lift heavy to get the benefits
One of the biggest myths about strength training is that it requires heavy weights or a high-level background to be effective.
It doesn't.
Bodyweight movements, light dumbbells, kettlebells, resistance bands — all of it counts. What matters most is progressive overload: consistently challenging your muscles slightly more than they're used to. That can happen with a 10-pound dumbbell just as effectively as a 100-pound barbell, as long as the training is structured and intentional.
The right coach can build a strength program that fits where you are right now — your current fitness level, your schedule, and your goals.
How strength training fits into CrossFit
At CrossFit Una Stamus, strength training isn't a separate thing you have to add to your routine. It's baked into every week.
Our programming intentionally blends strength work — deadlifts, squats, presses, cleans — with conditioning so that members are building both fitness and durability at the same time. You're not just getting tired. You're getting stronger in ways that carry over into real life.
And because every movement is taught and coached, you learn proper mechanics from day one. That means you build strength safely, reduce your injury risk, and make progress that actually sticks.
The bottom line
If your current fitness routine doesn't include any strength training, you're missing one of the most powerful tools available to you. Not because you need to look a certain way — but because your body deserves to be strong, resilient, and capable for as long as possible.
Whether you're 25 or 65, new to the gym or coming back after years away, strength training has a place in your routine. And at CrossFit Una Stamus, we'll help you figure out exactly what that looks like for you.
