See what our customers are saying about the O2Trainer
Amazing cardio improvement in just one week
Noticed huge cardio improvement after first week - no longer winded during physical labor in oilfield. Heard about it on Joe Rogan podcast and had to try it.
Elevated workout intensity and athletic performance
Training with O2Trainer and Mass Suit elevated workout intensity beyond any routine. Increased speed, power and endurance - game scenarios now feel slowed down.
Significant endurance gains after one month
After one month: breathes easier, runs faster, trains harder, fights longer. Noticed difference in couple weeks, significant endurance improvement after a month.
MMA training game-changer in just one week
Fast shipping, tremendous difference after one week. Does MMA 3 hours straight - was winded before, now barely breathing hard. Another great Bas Rutten product.
Perfect for beginners - huge lung capacity gains
Multiple resistance levels work for even out-of-shape people. Started one week ago and already noticed huge difference in lung capacity while running.
Updated version perfect for parkour training
Fast delivery, received updated version. Using it to improve stamina for parkour - very cool product, will update with impact results.
Maximizes cardio conditioning for cycling and running
Using for few months - extremely helpful for cardiovascular endurance and lung capacity. Incorporating into bicycling and running maximizes cardio conditioning.
Best breathing device - superior design
Out of all breathing resistance devices, this is the best. Can actually wear while training without tube sticking out. Suggests adding exhale resistance for faster capacity gains.
Incredible stamina gains with Krav Maga training
Uses with Krav Maga and Bas Rutten MMA Workout - challenging combination! Noticed remarkable stamina gains in short time with O2Trainer.
Brutal training, impressive 3-week results
3 weeks of use with impressive results. Training is brutal but stamina and endurance increased significantly. Performance with O2Trainer improved drastically.
High-quality materials, unique diaphragm training
Chose over high altitude trainer - very impressed with quality. High-grade polymer with biodegradable rubber housing. Only trainer that works diaphragm and increases lung capacity.
Accelerated weight loss and workout intensity
Lost only 1 lb in 4-5 weeks before O2Trainer. Lost 3 lbs in first week with it. More calories burned, higher intensity, more sweat, longer heart rate recovery.
Best respiratory trainer - brilliant simple design
Best respiratory trainer of many tried. Simple, brilliant design. Heard about from Bas on Joe Rogan podcast. Intense workout with this device.
Asthma patient - no inhaler since April
Had lung infections and bad asthma attacks. Uses O2Trainer daily - stamina improves, workouts last longer, lungs stronger. Haven't used inhaler since April. Unlimited stamina now.
SWAT instructor sees results after 2 days
Used during two workouts, trained without device on day 3. Breathing seemed more relaxed and efficient. Surprised by positive results after only two days.
Racing competitor confirms lung strengthening
Well-made device that works. Competes in short distance running and climbing - air processing paramount when racing. Strengthens lungs and diaphragm as advertised.
Couple's success - dancing, laughing, singing
Gifted set for husband and wife. Results really started showing after adding O2Trainer. Lung stamina made world of difference - now dancing, laughing and singing simultaneously.
Saxophonist plays longer, stronger notes
Professional musician noticed difference after first few uses. Like training uphill with weights, then racing downhill. Lung capacity taken to new level - more air through horn, longer notes.
Teen with exercise asthma - no inhaler needed
15-year-old with exercise-induced asthma since age 6. After one month, no inhaler needed during 3-hour training sessions of interval training, cardio and bag work. Got life back.
Lifelong asthma - replaced inhaler completely
Asthma ruled life since childhood, prevented organized sports. Replaced inhaler with O2Trainer - strongest cardio ever. Two months later: level 13, no inhaler, 15-minute rolls without attacks.
Elite athlete - needs stronger resistance
Several months use confirmed it works - runs farther and faster. Reached highest level and needs something stronger. Runs over 10 miles with O2Trainer easily now.
