Fitting training around work, family and everything else life throws at you isn't always easy. But a gym session doesn't need to involve endless sets, exercises and pieces of kit to be effective. Former rugby player and coach Sam Warburton's simple shoulder and arm workout is a prime example.

'I only now train 2 sets per body part,' he shared in a recent Instagram post. The coach also pushes the last sets of each exercise close to, or to failure, allowing for drop sets, pauses and partial reps.

'Failure of one full range of motion rep doesn’t mean failure,' he added.

Warburton's approach to training also allows for flexibility. Instead of focusing on rep ranges, he simply pays attention to effort levels.

'You can grow with 4, and grow with 25, provided the effort is there,' he explained. 'I don’t worry whether I hit 9, 10 or 13. As long as it’s hard.'

For each session, he says 12-15 sets can be enough if you're working close enough to failure. And, for busy schedules, the good news is that 3-4 sessions per week is all you need.

How to Do the Movements

Seated Shoulder Press

Sit upright with your back supported and hold a dumbbell in each hand at shoulder height, palms facing forwards. Press the dumbbells overhead until your elbows are extended, then lower them under control back to the starting position.

Seated Bicep Curl

Seated Lateral Raise

Stand facing a high cable with a rope attachment, holding one end in each hand, thumbs up. Keep your elbows pinned to your sides and extend your arms until they're fully straight. Squeeze your triceps at the bottom before slowly returning to the starting position.

Seated Face Pull

Sit facing a cable machine with a rope attachment set around head height. Pull the rope towards your face, keeping your elbows in line with your shoulders and hands in line with your head, splitting the rope. Squeeze your shoulder blades together before returning the rope under control.

Dumbbell Shrug
