How To Use
RESFIT Trainer
Follow these steps to get the most out of your RESFIT Breathing Trainer. Simple, effective, and built for any fitness level.
Make sure your RESFIT Trainer is clean before use. Rinse with warm water and let it dry. Place the mouthpiece in your mouth and bite down gently on the inner sides to secure it in place.
Rotate the dial to your desired resistance level. Start at Level 1 if you are new to breathing training. The resistance should feel challenging but not uncomfortable — you should be able to complete a full breath cycle without straining.
Sit or stand upright with good posture. Inhale deeply through the mouthpiece until your lungs are full, then exhale fully through the device until you are almost out of breath. Focus on slow, controlled breathing — not speed. Complete 10 breaths per set.
After each set of 10 breaths, remove the device and breathe normally until you recover. Then repeat for 2 to 4 sets. Train daily — consistency is what drives results. Most users report noticeable improvements within 2 to 3 weeks.
Find Your Level
Progress through 4 resistance levels as your breathing muscles get stronger. Don't rush — each level builds the foundation for the next.
Lightest resistance. Ideal for first-time users or those recovering from inactivity. Builds initial breathing awareness.
Weeks 1–2Moderate resistance. For users who have completed 2+ weeks of consistent training and feel comfortable at Level 1.
Weeks 3–5High resistance. Recommended for active athletes looking to push their respiratory limits and maximize endurance gains.
Weeks 6–8Maximum resistance. For elite athletes and those who have fully adapted to previous levels. Only use when Level 3 feels easy.
Week 9+Each daily session lasts approximately 5 minutes. Short enough to fit into any schedule, powerful enough to build real results.
Complete 2 to 4 sets of 10 breaths each day. Rest between sets by breathing normally until fully recovered before the next set.
Train daily, preferably before meals. You can use RESFIT as a warmup before workouts or as a standalone breathing session at any time of day.
Most users report improved breathing control and reduced breathlessness within 2 to 3 weeks of consistent daily use.
