This is a Glutes workout, hamstring workout and back workout... all in one session! This dumbbell routine will strengthen your entire posterior chain! You will need a pair of dumbbells, a steady chair for Bulgarian lunges and a mat! Also a wall simply to use for balance during single leg calf raises! The timer will be on 45 seconds of work, with 15 seconds rest. There is a staple exercise combination after every 3rd exercise... variations of the Romanian deadlift. I have chosen this exercise as it is a fantastic movement to involve the hamstrings, glutes and back! Your forearms will also be tested!! You can perform with one dumbbell if preferred, particularly towards the end if forearms and grip feeling it tough!
