Fitness Coach: Silna Arc

Build muscle and add strength - by training with a personal coach in your pocket. At home, in the gym, anywhere. Silna Arc compiles a complete hypertrophy program for your body, your equipment, and your schedule, then adapts it after every set you log.

A coach, not a template

Whether you want to work out 6x/week for 60 minutes or 2x/week for 30 minutes each - Silna Arc builds a full workout plan just for you to make sure you get the most out of your time. Every exercise comes with concrete weight and volume recommendations and is adjusted continuously based on your individual performance. Day in, day out.

Built with a strength coach

Silna Arc was built with Alex, a strength coach with a fitness economics degree and years of personal training behind him. His methodology - how a serious coach actually decides what you should lift today - is what Silna Arc runs on. Evidence-based hypertrophy training, based on real state-of-the-art science.

Adjustments you can see

Silna Arc adjusts your workouts based on today's performance - right there, in the gym. The weight moves easier than usual? Your next sets adjust. Rough day? Your next sets adjust. As you get stronger, the weights adjust. Your body needs a deload? Silna Arc notices and schedules it for you.

Plateau Detection & Breakthrough

Your plan automatically detects plateaus and adjusts to help you break through it with targeted recommendations.

Your exercises, your equipment

Tell Silna Arc what you have - a full gym, dumbbells, a doorway pull-up bar - and it builds around it. Hate an exercise? Swap it. The library is organized by purpose, so every swap respects the rest of your plan.
