The problem
Fatigue, off days, sluggish sessions. The answer may surprise you.
Your body relies on glucose to power movement, training, and recovery. During prolonged or intense activity, energy demands increase, which can affect how you feel during and after exercise. What can often feel like fatigue, low energy, lack, or an off day may simply be a fueling issue. Understanding your glucose can help you recognize the patterns behind your energy and make more informed decisions about your fueling and recovery habits.2,8
