Like many of you, I love getting my sweat on with a killer cardio session. Nothing quite makes me feel as satisfied with yourself—like you’ve really put in an honest effort and accomplished something great for your body and mind!
However, as a personal trainer and a gym rat, I’ve seen my share of horrendous and potentially dangerous cardio moves. So the next time you’re in a spin class or on the treadmill, ask yourself: Am I guilty of any of these cardio crimes?
Registered dieticians at the American College of Sports Medicine claim that endurance athletes should never workout without fuelling up first and foremost. Eating before a workout is like fuelling up a car before a long journey, it guarantees that the body starts with a full tank of glycogen, so even for a 90 minutes hot yoga session, fuelling up will ensure our bodies have enough energy during a workout as it burns glycogen (energy stores in the muscle cells).
Even if you just plan a short 30-minute run, starting out with zero fuel could zap glycogen stores quickly and leave you light-headed, weak, and quickly fatigued. However, base your fuel on your workout needs. For instance, hydrating and eating a small piece of fruit should do it prior to a 30 minute elliptical session.
