I'm Building An App, Here's Why:

I've spent the last few months building something I've wanted to exist for a long time.

An app called Capacity.

Here's the problem with most training apps: they give you a program that's really just a fixed set of workouts. They don't know anything about you: your training history, your goals, if your squat is strong while your bench press sucks, or if you're running your easy days way too hard. They just tell you what to do and hope it works.

Capacity is different. It builds your program around your schedule, your experience level, and your goals. Then it adjusts based on what happens when you train.

It's not a template or a plan some coach wrote for a generic person. It's a program that's yours from day one.

A few things it does that nothing else does:

Your lifting and running are programmed together. Most people either lift and ignore running, or run and throw in some curls. Capacity programs both and manages the interference between them, so progress on one doesn't come at the cost of the other.

It adjusts before you train, not after. Every session starts with a quick readiness check. Sleep, stress, soreness, energy. Rough night or a brutal week, and the app scales that day's session down before you start it. A really bad day, and it recommends rest instead.

Every lift progresses independently. Your squat might be on a different timeline than your bench. A newer movement might progress linearly while an advanced one runs wave cycles. The app tracks each lift separately and makes decisions from that lift's history.

Every number comes from your data. Your weights come from the sets you logged. Your paces come from your own results. Deloads only show up when your numbers say you need one. Nothing in this app is based on assumptions about some average lifter.

It's in beta testing right now with a small group, and I'm opening it up in stages.

Early access goes out in waves as the app gets closer to launch. Put your name on the waitlist and I'll email you when your spot opens: Join the waitlist

Beta Testers Needed!

And if you're interested in helping me beta test now: testing means you use the app for your real training, you hit bugs, and you tell me about them. In exchange, you get the app months before anyone else and a say in what gets fixed first and what features are added.

Reply to this email with the word BETA and I'll send you the details.

Mike

Why You Don't Need To Lift More Than 3 Days Per Week
Let’s get this out of the way: You don’t need to lift 5–6 days a week to be strong or to add size. Especially if you’re also running, biking, rowing, or doing any serious endurance work. In fact, lifting that often will probably make your hybrid performance worse. If you're trying to balance strength and endurance, you just need to lift enough to achieve your goals. The key to hybrid style trai...
Can You Build Muscle, Get Stronger, and Improve Endurance at the Same Time?
You’ve probably been told it’s impossible. That you can’t build muscle and run faster. That trying to get strong while improving endurance is a waste of time. That you have to “pick one goal and stick to it.” There’s a grain of truth in that advice, but it’s not the full story. Because with the right strategy, you can build muscle, get stronger, and improve your endurance at the same time. The ...
Why Measuring Veggies is a Waste of Time
Let’s be honest: if you’re logging every gram of spinach and every carrot stick you eat… it might be time to relax. That's a great way to burn yourself out and make it so you dread counting calories. Fat loss takes discipline, but it also takes common sense. And spending 5 minutes figuring out how many grams of broccoli you ate isn’t just unnecessary. In fact, it will likely make your diet hard...
