What is intra workout nutrition?

Intra workout products are things you take during a session rather than before or after: electrolytes for fluid balance, carbohydrate for fuel, amino acids, and gels for endurance work on the move. They all mix thin and are meant to be sipped rather than drunk in one go.

Who needs them is narrower than the category suggests. For a resistance session under an hour, water covers it and your stored glycogen is ample. These products earn their place once sessions get long, hot or repeated: endurance training and events, two sessions in a day, heavy sweating, and high volume blocks where fuel and fluid genuinely run down.

How it is usually used

Mixed into 500 ml or more of water and sipped steadily through the session. For prolonged endurance work the common guidance is 30 to 60 g of carbohydrate an hour, built up gradually in training rather than attempted for the first time on event day.

Compare the range

TypeUsually chosen forWhat makes it different
Electrolytes & Hydration Long or hot sessions and heavy sweating Sodium, potassium and magnesium to replace what is lost in sweat. Sodium is the figure that matters most.
Carbohydrates & Endurance Sessions beyond about ninety minutes Drinkable fuel, usually maltodextrin or cluster dextrin, for when stored glycogen starts to limit pace.
Energy Gels & Sachets Running and riding, fuel on the move The same job as a carbohydrate drink in a pocket sized sachet. Needs water taken alongside it.
BCAAs & EAAs A light drink to sip while training Amino acids with almost no kilojoules. EAAs supply all nine essentials and are the better choice for muscle.

Frequently asked questions

Do I need anything during a one hour gym session?

Water, in almost all cases. An hour of resistance training does not deplete glycogen enough to need fuel, and unless it is hot or you sweat heavily, your meals cover the electrolytes. Intra workout products start to matter beyond that.

Electrolytes or carbohydrate, which do I need?

Depends on what is limiting you. If you are losing a lot of sweat but the session is not long, electrolytes. If the session is long enough that you are fading rather than cramping, carbohydrate. Long events in hot conditions often need both.

How much carbohydrate per hour?

The usual guidance for prolonged endurance exercise is 30 to 60 g an hour. Start at the lower end and build, because tolerance is trainable and going straight to a high rate commonly causes stomach trouble.

Are BCAAs worth taking during training?

Only as a light drink. If your daily protein is adequate, BCAAs add little, and EAAs or a complete protein are better for muscle. Where they genuinely suit is wanting something flavoured and nearly kilojoule free to sip through a session.

Can I just use a sports drink?

For many sessions, yes. A standard sports drink carries both carbohydrate and electrolytes and is perfectly adequate. Powders and gels let you control the concentration and carry more fuel in less space, which matters for longer events.
