Upon completing another brutal leg exercise, drenched in sweat and desperately trying to recover my ability to get up and walk around the gym, I asked Joe the question every pro bodybuilder must have heard a thousand times: Is there anything I could be eating, drinking or taking that would make this workout easier?!
Joe just chuckled and gave me a look I knew meant “easy” and “leg day” should never be put together in the same sentence. Undeterred, I pressed on. I told him I was thinking I should pound some sugar right before the workout began. Maybe eat a banana or, heck, even a candy bar. Would that work?
Joe considered the question for a moment. “Tom Platz (aka ‘The Quadfather’) used to sip a can of Coke between sets,” he said. “But if you want something more than an anecdotal answer, we need to ask Alan.”
He was referring to Alan Aragon, a nutrition scientist who has been publishing peer-reviewed research for more than 25 years. Apparently, he is also a super-nice guy who will take the time to answer random fitness questions from his friends. Joe whipped out his phone and sent off a message. Minutes later, we had an answer.
As it turns out, Alan has just completed a book that provides in-depth, evidence-based answers to this question and many others. It’s called Flexible Dieting, and it’s due out on June 7. You can check out the table of contents and pre-order the book here.

In the meantime, Alan was kind enough to give us what he called the “nutshell version” of the answer to our question:
If you’re consuming total daily carbs at a minimum of about 3g/kg (the optimal range for strength-oriented athletes is 3-8g/kg), your resting and ongoing glycogen levels will support typical-volume, resistance-training bouts — regardless of the timing of carb doses.
If your training session exceeds 90 minutes, then it can be beneficial from a performance standpoint to consume a dose of about 1g/kg within 1-2 hours pre-exercise, or consume 30-60g per hour during training.
Let’s translate this into actual numbers for someone like me. I weigh north of 100kg and work out for close to two hours each training session. That means my daily carb intake should be at least 300g, according to Alan, and I should consider consuming 100g of carbs before my workout or 30-60g twice during my workout.
That’s about five bananas in the first case, or two cans of Coke in the second case.
I guess The Quadfather was onto something!
