Inspiratory Muscle Training (IMT) has been studied for decades by sports scientists. Research shows that strengthening the breathing muscles improves endurance, reduces breathlessness, and increases performance in runners, cyclists, swimmers, and everyday athletes.

✔ IMT improves running performance and reduces breathlessness

A 2023 randomized controlled study found that IMT significantly improved 1-mile running time and reduced perceived breathlessness after only 4 weeks of training.

✔ 20–30% increase in respiratory muscle strength

Researchers found that IMT increased respiratory muscle strength by up to 30% in healthy adults, improving oxygen efficiency and breathing power.

✔ Reduces fatigue of breathing muscles during exercise

Research shows IMT delays respiratory muscle fatigue, allowing athletes to maintain pace longer with less effort.

Real results

Before vs after AeraFlow PRO

What most athletes feel before using a breathing trainer – and the changes they notice after a few weeks of consistent sessions.

Before AeraFlow PRO

Shallow breathing, early fatigue, and inconsistent bracing.

Common struggle
  • Breathing feels rushed and shallow during heavy sets or cardio.
  • Gassing out early and needing longer rest between efforts.
  • Hard to keep a tight brace under heavy weight.

Most people never train their breathing muscles directly, so they hit a ceiling long before their actual strength or endurance maxes out. >>>(below is a smokers lung's)

After consistent use

Deeper control, stronger lungs, and longer-lasting performance.

2–4 weeks
  • Breaths feel deeper and more controlled,
  • Greater endurance and shorter rest times.
  • Stronger bracing and stability on squats, deadlifts, and presses.

With just a few focused minutes a day, athletes report noticeable improvements in breathing strength, control, and overall performance. >>>(below is a smokers lung's who quit with AeraFlow PRO)
