If you want to build stronger arms and upper body muscle, you may spend hours at the gym lifting weights. This is an effective way to train, but it’s not the only way. Fortunately, you can also get results in just 5 minutes a day with this short routine from Chris Hemsworth’s personal trainer.
All you need to get started is a pair of weights. If you’re at the gym, a fixed-load set of dumbbells will do, but we recommend the best adjustable dumbbells for home workouts since they combine several weights for easy storage and you can quickly change the load.
