Total beginners, who have only ever trained at home with no guidance from a personal trainer, should start with weights anywhere from 2kg-6kg, says Zara. “You don’t want to start too heavy and end up losing confidence when you can’t perform exercises,” she says.

If you have been doing bodyweight training for a while and already feel pretty strong (those press-ups really pay off, you know), you might be ready to step up to medium-sized weights. For that, you could opt for dumbbells that weigh around 6-10kg. Anything over that would be classed as ‘heavy’ when it comes to your home workouts - perfect for those who have swapped gym-based training for home workouts.

Dumbbells in their teens may sound light for those who regularly squat 40kg plus at the gym, but remember that barbells are a different territory. Squatting with a dumbbell will require you to get the weight onto your shoulders or hold it at your chest, whereas the racks in the gym are designed to take this extra strain off the movement.

Isolation exercises will also require lighter weights than compound movements: you will probably be able to row more than you can bicep curl, for instance.
