Intra-Workout Nutrition: Should You Eat During Training?

Intra-workout nutrition - consuming carbohydrates, protein, or amino acids during a training session - is relevant for a minority of athletes and training scenarios. Understanding when it matters and when it's unnecessary saves you money and simplifies your training routine.

When intra-workout nutrition is warranted: training sessions exceeding 75-90 minutes, particularly high-volume strength sessions or long conditioning work. In these extended sessions, glycogen depletion becomes a real performance limiter in the later portions of the workout. A carbohydrate source (25-50g per hour) consumed during the session maintains blood glucose, delays glycogen depletion, and preserves performance in the final sets. Suitable options: sports drinks, a banana, dates, or fast-digesting carbohydrate gels.

When intra-workout nutrition is unnecessary: training sessions under 60-75 minutes. If you've eaten a pre-workout meal 1-2 hours prior containing adequate carbohydrates, blood glucose and glycogen levels are sufficient for a typical 45-75 minute strength or conditioning session without any food during the session. Consuming BCAAs or EAAs during training has marginal benefit when pre-workout protein intake is adequate. The exception: fasted training where no pre-workout meal was consumed - in this case, 10-20g of protein or EAAs before or during training can prevent excessive muscle catabolism. Don't overcomplicate the peri-workout nutrition window. For most recreational athletes training 45-75 minutes, pre-workout and post-workout nutrition are sufficient.
