Nike running shoes featuring Flywire lace support for a secure fit and a lightweight, breathable mesh upper.

The Rucking App is officially live on Android.
I built this after realizing watches and fitness apps massively undercount rucking. This app uses your weight, pack weight, distance, effort, and pack type to give you a much more realistic calorie estimate—based on the same formulas powering my rucking
I Built the Rucking App I Wish I Had When I Started
I finally built the rucking app I wish I had when I started my 90-lb weight loss journey. It tracks real ruck calories using your bodyweight, pack weight, distance, effort level, and pack type—things most fitness trackers ignore. Watch the demo, see it in action on the trail, and grab it now on Google Play.

The Irony of Ozempic: Paying for the Willpower You Refused to Build
Ozempic is marketed as medicine, but it's really a subscription to self-denial. You're not gaining health — you're outsourcing willpower, gambling with your hormones, and calling it progress.

How Many Calories Does Rucking Burn? Here’s the Calculator I Built to Find Out

Try searching “kratom” on Facebook. You’ll get a warning that content has been removed. But scroll long enough and they’ll sell you 7-OH — a synthetic compound known to cause shutdown in tiny doses. Welcome to the platform that profits off silence.
Facebook Won’t Let You Search Kratom — But It’ll Sell You 7-OH Candy That Can Kill You
Facebook blocks users from searching the word “kratom,” but still allows paid ads for unregulated 7-OH products — a synthetic compound known to cause respiratory shutdown in small doses. This article breaks down the platform’s dangerous double standard.

Imagine buying an ice cream cone and ending up in an ambulance. That’s how close the line is with 7-OH — a synthetic kratom alkaloid disguised as candy and sold without warning. If your body stops breathing, it’s not a trip. It’s a shutdown. Read the truth now.
7-OH: You’re Either Lucky… or You Ain’t
Sold in candy-colored packaging, 7-OH is one of the most dangerous substances in your local head shop. With dosages so small you can’t see them, and risks that shut down your body, this synthetic kratom compound isn’t a vibe — it’s a coin flip with death.

I don’t drink. I don’t smoke. I’m a certified trainer who lives clean.
But 7-OH kratom wrecked me. Physically, emotionally, mentally.
If you’ve seen the ads, read this first. This stuff isn’t safe — it’s silent chemical warfare dressed as a supplement.

If I Keep Seeing Ads for 7-OH, I’m Posting This Article Everywhere
I don’t drink, don’t take prescriptions, and I live clean. But one small dose of 7-OH kratom wrecked me. Stomach shut down. Mood collapsed. I felt like I was dying. This isn’t “just kratom” — it’s a synthetic opioid in party packaging. And nobody’s warning you how dangerous it really is. So I am. Somebody’s gotta stand up.

I used to bike 30–40 miles a night trying to lose fat — but I ended up losing muscle and gaining fat instead. This article explains how gluconeogenesis works, why too much cardio can backfire, and how rucking helped me flip the script.
How I Gained Fat While Biking Too Much — And Why I Switched to Rucking
Too much cardio while under-fueled can actually backfire — leading to muscle loss, metabolic slowdown, and even fat gain. Here's how I learned the hard way and why I switched to rucking to preserve muscle and build strength more efficiently.
