Because this exercise requires you to work with your arms extended at all times, you might feel the burn pretty early on. It also means you’ll be working your shoulders, upper arms and forearms.
Hold a pair of dumbbells on either side of you and bend your elbows slightly. Raise your arms straight to your sides until the dumbbells are at shoulder height, engaging the core and keeping your feet shoulder-with apart. Your body should look like a cross or the letter “t”. Hold the move for a second at the top and then bring the weights down in a controlled manner.
