Intra-workout drinks are sipped during training. They make the biggest difference in long or very hard sessions, double days, endurance work and fasted training.
Find the right one
- Long, hard sessions: fast-digesting carbs such as HR Labs Carb Up
- Endurance or hot days: carbs plus electrolytes
- Fasted or dieting: amino acid formulas
- Add to your own drink: HR Labs Level Up V2 (unflavoured)
Mix into 500–750ml of water and sip through your session. Fast UK delivery from Insight Supps.
