Why We Built CaliStack

We Built a Calisthenics App Because We Got Lost Learning Handstands

On March 1st, 2025, I could barely do 15 push-ups and maybe 3–5 pull-ups consistently. At the same time, my social media feed was completely flooded with calisthenics videos. People doing handstands, muscle-ups, front levers — making it all look effortless.

So naturally, I tried a handstand the next day. I kicked up, lost balance instantly, and slammed onto the floor. My wrist hurt. My ego hurt more. For a moment, I completely gave up on calisthenics.

Later that night, I opened YouTube and started searching: “How to learn handstand.” That single search changed everything.

Every tutorial told me something different. One creator said start with wall handstands. Another said build shoulder strength first. Someone else said frog stands are mandatory. Suddenly I discovered movements like Crow Pose, Pike Push-ups, Hollow Body Holds, Wrist Conditioning, and Scapula Control.

“A handstand is not one skill. It's a skill tree.”

That realization became the starting point of CaliStack. Most fitness apps tell you to do random workouts. But almost nobody explains progression clearly. Nobody tells beginners what should come next.

I didn’t need another workout app. I needed a roadmap. Something that answered: “If I can do push-ups… what should I learn next?”

That’s when I shared the idea with Riyas, the designer behind CaliStack. I expected him to say the idea was too complicated. Instead, he simply said: “Let’s build it.”

At first, progress was painfully slow. We downloaded dozens of fitness apps trying to understand how they structured workouts and progression systems. Most apps had huge exercise libraries. Very few had clarity.

“Beginners don't quit because they're weak. They quit because they're lost.”

Then came the hardest part: content production. We didn’t want to build another app that simply embedded random YouTube videos. We wanted original tutorials, original structure, and proper progressions.

The problem? We had no funding. No studio. No athletes. Nothing.

So I started messaging calisthenics athletes on Instagram every day. Most people ignored the messages. Some liked the idea but asked the obvious question: “What if the app never launches?” Honestly, I didn’t have a perfect answer.

Eventually, we built a small team of four people:

• Rishad (me) — app development and product structure • Riyas — UI/UX design • Irshad (Mallu Ninja) — calisthenics expertise and tutorials • Irshad — video production and marketing

Slowly, the project started feeling real. One tutorial became ten. Ten became fifty. Then the app slowly started looking like something people could genuinely use.

Today, CaliStack includes 228 workouts, 100+ tutorial videos, and structured progression systems designed specifically for beginners.

“Clarity beats motivation every time. You don't need to feel inspired every day. You just need to know what to do next.”

The funniest part? I originally started building this app because I wanted to learn calisthenics myself.

While building CaliStack, I learned Frog Stand, Crow Pose, Elbow Lever, Headstand, Handstand, Muscle-Up, Back Lever, and more. The movement that made me quit at the beginning eventually became the movement that pushed me forward.

CaliStack still isn’t finished. We’re still recording tutorials. Still improving workouts. Still refining the experience. But now beginners around the world are already using it to start their calisthenics journey.

And honestly, that alone makes the entire struggle worth it.
