After a pulmonary surgery in 2018, Chuck, our co-founder, lost the right upper lobe of the lung forever. That surgery significantly decreased his vital capacity and made him run out of breath quickly. To help Chuck restore his vitality, we decided to search for a solution to help him train his respiratory muscle and increase accessible lung capacity. And OPUMP comes. Now Chuck ranks TOP 3 in lung capacity in our group. Our excellent singer, adventurous hiker, and joy maker are back.

After numerous scientific studies and countless prototypes after the original conception, we decided to take it to the public so everyone on the earth could benefit from it.
