Armed with the right workout, you only need 20 minutes to strengthen your biceps and triceps, and increase your upper body power. If you’re able to do a 20-minute arms workout once or twice a week and back up your efforts with a healthy diet and good sleep, you’ll quickly start to see impressive results.
If you have a set of the best adjustable dumbbells you can change the weight as required for each exercise, or you can use just one light set of dumbbells for the whole workout if you don’t have a range of weights available.
