The ultimate Muscle-building trisets workout

Tri-set 1

Perform one set of the barbell squat, dumbbell lunge and sumo squat one after the other. Rest once you've completed the sumo squats, then repeat all three exercises for three rounds total.

Sets: 3

Reps: 8

Rest: None. Go straight into lunges

Stand with your feet more than shoulder-width apart and hold a barbell across your upper back with an overhand grip – avoid resting it on your neck. Hug the bar into your traps to engage your upper back muscles. Slowly sit back into a squat with head up, back straight and backside out. Lower until your hips are aligned with your knees, with your legs at 90 degrees – a deeper squat will be more beneficial but get the strength and flexibility first. Drive your heels into the floor to push yourself explosively back up. Keep form until you’re stood up straight: that’s one.
