Ask any fitness enthusiast and they will tell you about the importance of strength training. It’s a form of exercise that makes your muscles strong. Hence, the name.

You know the most common way of strength training? Yes, lifting weights mostly as dumbbells. Of course, there’re others like resistance bands. But dumbbells are the most popular. And rightly so, because they’re easy to use and scalable (available in different weight sizes).

This is a modern world, right? Everything is getting smart. I mean everything from cars to toothbrushes. So, why not dumbbells? I know why change something that’s working. Understandable. But dumbbells come with their own set of problems. They take up a lot of space. Also, they affect our productivity. Imagine looking for a dumbbell of a particular weight every 5 minutes.

For someone who’s serious about strength, they need to add barbells, kettlebells and resistance bands to their home gym kit as well. Yes, for a proper full-body workout. Now, all these bells and bands can be a mess. Confusing, time taking and space taking. The worst part? They aren’t smart.

That’s where Tonal, a home fitness company, comes in.

They’ve designed wall-mounted strength training digital equipment that replaces dumbbells and other strength training equipment. There’re a lot of buttons, modes and sensors. It’s more like having a strength-training coach.

Technically, the equipment uses a motor to generate resistance. And since it’s a motor inside, it adjusts weights swiftly. You can do hundreds of different strength exercises using it. No need to pause or change equipment.

Till date they’ve raised a lot of money from investors (and sports icons) like LeBron James, Serena Williams, and Maria Sharapova. I don’t know the sales data, but I’m confident that their great product is doing well.

Home fitness is going to be an enormous market in the next decade. People are becoming more health-conscious. They want to improve their health without spending a lot of time and money in a traditional gym setup. That’s where companies like Tonal are likely to do well.

The only problem? Tonal 2 (their latest version) costs around $4295. Yes, that’s high for many people. If they can work on their pricing, they will grow even faster.
