inspiratory muscle training increases diaphragm size and reduces breathlessness after hard effort
IMT stimulates adaptive remodeling of inspiratory muscles, including increased diaphragmatic cross-sectional area, which improves respiratory efficiency and reduces fatigue and dyspnea after strenuous exercise.
What this means for you
A stronger, larger diaphragm means your breathing muscles work more efficiently and tire out less quickly — so after a tough workout or a long day, that heavy, gasping feeling fades faster. Most people notice they can push harder before hitting their breathing limit, and recover their breath more quickly when they stop.
