Strength Training Is the New Cardio—And the Science Backs It Up

I used to think exhaustion was just part of getting older. I sit at a desk all day, sit on a couch at home, and maybe jog once or twice a week.  I thought I was doing “enough,” but I still felt worn thin.  And I wasn’t showing up how I wanted to for my family.

But every time I tried to get healthier with the newest cardio trend, it would fizzle out in a few weeks. It felt pointless, and the long-term health risks started to weigh heavier on my mind.

But turns out, strength training (not cardio) is the game changer I’d been missing. And the tool that helped me make it stick? A smart, compact home system called amp™.

Here’s how it helped me turn things around.

1. I’m finally burning fat and building strength, instead of just wearing myself out

I used to think cardio was the only way to “burn it off.” But all it ever left me with was joint pain, sore knees, and zero energy. What I didn’t realize is that strength training not only burns fat better, it helps keep it off for the long haul by building lean muscle and revving up your metabolism 24/7.

amp™ gave me access to over 450 AI-supported exercises and 20+ expert-led strength classes that targeted specific muscle groups. The app automatically adjusts my resistance as I improve, so I’m not left guessing or plateauing. And for the first time in years, I’m seeing changes I can feel: more energy, less belly fat, better sleep, and a stronger body that feels like it’s working with me, not against me.

2. I get real workouts done in 30 minutes or less without leaving the house

I don’t have the time (or mental bandwidth) for long gym sessions anymore. Between work, kids, and everything else, I need something that fits real life.

amp™ workouts are short, effective, and flexible. Whether I have 10 minutes between meetings or a half hour before the kids wake up, I can choose workouts based on my goals like mobility, fat loss, or building strength. No commutes. No wasted time. Just smart programming that respects my schedule and my body. (And if you’ve got a bit more time, amp™ does have longer programs available.) It’s the only solution I’m actually able to be consistent with. 

3. It’s fixing more than just my strength; it’s helping undo years of sitting

Years at a desk wrecked my posture and made my body feel older than it is. I’d started to accept stiffness and back pain as the norm.

amp™’s workouts are designed to restore mobility, build core strength, and improve joint stability. It’s not just about lifting heavier; it’s about moving better. I stand taller now. I feel more capable. And those daily aches that used to slow me down? They’re not running the show anymore.

4. I’ve finally stayed consistent because amp™ makes it fun and easy

This was my biggest hurdle. I’d always start strong and fall off two weeks later. But amp™ actually makes me want to keep going.

The app is smart. It tracks my progress, suggests new workouts, and even syncs with my Apple Watch so I can see how I’m improving. There are challenges, streaks, and even no-equipment options when I’m traveling. It even offers some gamified features like vertical jumps and drop sets to spice up my routine. Everything helps keep me consistent and motivated. And now, for once, I’m not just “trying to stay active,” I am active.

5. It fits my life and my space

We don’t have room for a full home gym. amp™’s setup is wall-mounted, sleek, and honestly looks good in the room.

It installs in minutes, and everything about it is engineered for simplicity. The spring-loaded arms lock into 10 height stations and 3 angles so I can hit every move with precision. The dial-controlled resistance is smooth and intuitive, and the built-in phone holder doubles as a wireless charger (small thing, big win).

Also, amp™’s design is safer than free weights, so I don’t worry if my kids are nearby.

I'm Taking My Life Back Every Time I Work Out

This isn’t just about fitness. It’s about showing up for my life. I’m more present, more patient, and more confident. I’m setting an example for my kids that health is something we take care of, not something we give up on.

If you’re stuck in the grind, tired all the time, and feeling like you’ve tried everything, you’re not alone. But there is a better way to feel strong again. Strength training is the key, and amp™ makes it actually doable.
