Building a physique takes a holistic approach. Your training, nutrition and body comp are one system. So why are you tracking them in three different apps?

One app. One system. Built to help you build muscle and lose fat.
Templates, social feeds, streaks and badges. None of these build muscle. None of these lose fat.
Progressive overload. Calorie and macro discipline. Body composition tracking. Pushing through plateaus. These are the bodybuilding fundamentals. ResistX is built around them.
It's not a coaching app. It's not a workout logger. It's not a macro tracker. It's the bodybuilding app: training, nutrition and body comp working as one system, every part connected, every part pulling toward the same outcome.
Evidence-based deep dives on training, volume, autoregulation and nutrition. The same thinking baked into ResistX.
RPE and RIR both measure effort, but they work differently for hypertrophy training. Here's which to use, when, and why it matters for your gains.
Most workout apps count total sets, not effective volume per muscle group. Here's why that matters and how to track it properly for hypertrophy.
ResistX speaks your language. It asks about your training phase, your split, your RIR comfort level, your physique goals. Because it was built by a bodybuilder, for bodybuilders.

Lifelong lifter and bodybuilder. Built ResistX because every app he tried solved one piece of the puzzle. Training, or nutrition, or body comp. Never all three. Never connected. Read more →
