Truth be told, a t-shirt bra is never recommended for light or intense workouts. Simply because it is not designed with the right sturdiness to support painless jumps, burpees, sprawls, and jogs. More so a sports bra gives complete coverage with flexibility so that you can easily get into those daunting yoga postures without having to worry about discomfort or exposure. A t-shirt bra may seem comfortable but will only land up restraining your movements.
