See why STAmina Apnea Trainer is one of the best apnea apps to improve the breath-holding time for freediving, scuba diving and spearfishing, as well as surfing, running, and other water sports with 6 different apnea tables types. ■ FREEDIVING & SPEARFISHING APNEA TRAINER FEATURES: ◉ 6 APNEA TABLE OPTIONS STAmina Apnea Trainer can create / generate custom apnea (exercises that are automatically created based on the maximum breath-hold and match the user’s level) or let you select from the following customizable table types: - O2 deprivation table – accustoms a body to lower oxygen levels. This is achieved by increasing the amount of time that you hold your breath on each attempt, while the resting time is fixed. - CO2 Tolerance table – helps a body to adapt to high carbon dioxide levels. This is achieved by decreasing the length of resting time between fixed breath-hold periods. - Wonka table – a variation of CO2 tables. Apnea timer starts after the first contraction, the rest time takes one breath. - Mix table – tables where apnea time increases and rest time decreases with each round. - Custom table – allows mixing of different approaches to create a custom training, thus generating the most effective training program. - Pranayama – a breathing technique to decrease stress in the body and relax the nervous system. ◉ APPLE HEALTH SYNCRONIZATION ◉ PERSONALIZED TRAINING WITH VARYING DIFFICULTY When you start working with the application, you set your personal record in breath holding.
