Forge Fit is a workout system and training center located in Indianapolis, IN. Our programs and diet plans – developed by owner and fitness instructor Marcia Erne – are designed to help you feel great, sweat hard, and work towards the best version of “You.”

Forging is the process of taking heat and energy to create something new. It also means moving forward towards a lofty goal. Our workout and group classes are designed to get you up, active, eating right and feeling ready for anything.

Forge Fit Process

Our strategy is simple: We build a partnership with you to help develop and meet short term goals. Every time you knock out a goal, we’ll strive towards a new one. Your progress is the #1 measure of success.

There are no excuses allowed at Forge Fit- it takes tons of work to forge a new “You.” We’ll work with you to overcome any barriers to working out and eating right. Can’t find time for even a small workout? Chances are we can find 30 minutes in your daily routine to go for a run and focus on a quick progress goal. We’re here to help you find it.
