Noticeably absent from McLaren’s suggestions is Macron’s favoured exercise: boxing. “Boxing is actually absolutely terrible for growing muscle,” McLaren says, “it’s a cardiovascular exercise, so it’s more to do with heart rate and technique.

So, your biceps may look bigger when boxing because you’ve got a lower fat percentage, but you won’t necessarily put on any muscle at all.”
