Find Your Crew

Inertia Fit is built for lifting with friends. Here's how to connect with your crew:

Search for Friends

Search by username to find friends you already know. Send a friend request and start seeing each other's workouts in your activity feed.

Suggested Friends

Discover new connections through mutual friends. When you and another user share friends in common, they'll appear in your suggested friends list.

Join Your Gym

Set your gym location to find other Inertia users who train there. A great way to connect with people you see at the gym but haven't met yet.

Your Crew Dashboard: Once you've added friends, the "Your Crew" screen shows who's been active, who's lifting right now, and your training history with each friend.

Track Your Workouts

The tracker stays out of your way so you can focus on lifting. Choose the approach that works for you:

Quick Workouts

Fastest

Jump straight into logging without any setup. Start a quick workout, add exercises as you go, and log your sets. Perfect for when you want to just get lifting.

Create a Split

Structured

Build a structured program with your split and workouts defined upfront:

  1. Create your split and add your workouts at the same time (e.g., "Push/Pull/Legs" with "Push Day", "Pull Day", "Leg Day")
  2. Add exercises to each workout from the exercise library or create your own
  3. Start any workout from your split and log your sets

Use a Template

Ready to Go

Skip the setup entirely with pre-built programs. When creating a split, choose a template and all workouts and exercises are already configured:

  • Push/Pull/Legs - Classic 3-day split by movement pattern
  • Upper/Lower - Simple split dividing upper and lower body
  • 5-Day Bro Split - Traditional bodybuilding, one muscle group per day
  • Full Body 3 Day - Hit everything three times per week
  • HIIT Circuit Training - High-intensity interval circuits
  • Cardio and Strength Hybrid - Mix of lifting and cardio

You can also browse community templates created by other users—real programs from real lifters.
