NASM Group Personal Training Specialist (GPTS) Practice Exam

For a 60-minute GPTS class, staying hydrated throughout the workout is essential to maintain fluid balance, regulate temperature, and support muscle function. The best approach is to sip water as needed during the session rather than waiting until after it ends, so you replace fluids lost to sweat and keep performance steady. If the workout is intense or you’re in a hot environment, using an electrolyte-containing drink helps replace sodium and other minerals lost in sweat, reducing the risk of cramps and dizziness. Drinking a full liter before class can cause stomach discomfort and doesn’t address ongoing fluid losses, while avoiding fluids altogether increases the risk of dehydration. In short, maintain regular, moderate hydration during the session, with electrolytes added when sweating heavily.
