10 Simple Arm-Strengthening Exercises

1. Lateral Raise (Side Raise)

  • Standing tall with your knees slightly bent, hold a dumbbell in each hand and hang your arms down by your sides.
  • Maintaining a slight bend at your elbows, raise your arms up and out to the sides, until they are level with your shoulders – make sure that your palms remain downward-facing).
  • Lower your arms slowly, and repeat 8-12 reps.

2. Overhead Extension

  • Standing with your feet hip-width apart and your knees slightly bend, grip a dumbbell with both hands.
  • Reach your hands up, over, and behind your head, holding the dumbbell in a vertical position, keeping your wrists straight.
  • Bending your elbows, lower the dumbbell further behind your head – make sure to keep your elbows pointing towards the ceiling and your uppers arms in close to your head.
  • Straighten your arms back upwards and repeat.

3. Push-Ups

  • Lying face down on the floor with your feet approximately 15-20 cm apart, place the palms of your hands flat on the ground, holding them slightly further apart than shoulder-width.
  • Keeping your body long and straight, move up onto your toes and raise your body off the floor using your arms until they are extended fully.
  • Then, slowly bend your elbows and lower your chest back towards the ground.
  • Stop approximately 10-15 cm before touching the floor with your stomach. Maintain a straight back and legs as you do.
  • Push yourself back up into the original position and repeat.
  • If this is too difficult to start, you can do an easier version with your knees on the floor. Even simpler still, you can use a wall and do this exercise standing up, with your feet positioned approximately 50 cm from the wall.

4. Tricep Push-Ups

  • Get into the push-up position with straight arms, but with your knees on the ground and your feet in the air – your hands need to be closer together than a regular push-up and under your chest.
  • Tightening your core muscles, bend your arms, and bring your chest down towards the ground. Keep your back straight and your upper arms closer to your body – your elbows should be pointing back behind you, not out to the side.
  • Straighten your arms back to the starting position and repeat.

5. Bicep Curl

  • Standing with your feet shoulder-width apart, hold the dumbbell in your hand.
  • Holding your palms forwards, bend your elbows and raise the dumbbell up towards your shoulder.
  • Slowly lower your arm back down to the starting position and repeat.

6. Dumbbell Row

  • Holding a dumbbell in one hand with your other hand and knee resting on a bench, keep your back straight and your elbow slightly bent with your palm facing inward.
  • Ensure that your bent knee (on the bench) is aligned under your hips and your hand under your shoulder.
  • Engage your core and squeeze your shoulder blades together, lifting the dumbbell upwards until your upper arm is parallel to the ground, with your elbow behind you.
  • Return to the starting position and repeat, followed by switching sides for another set.

7. Two-Arm Kettlebell Swing

  • Standing with your feet apart by a shoulder-width, hang your arms in front of you whilst holding a kettlebell with both hands.
  • Bending your knees, lower the kettlebell downwards between your knees.
  • In one swift movement, straighten your legs out of the squat whilst swinging your arms forwards and up to eye level – the kettlebell should feel practically weightless as it reaches the top of the movement.
  • Either repeat for a set number of reps or continue the movement to time sets.

8. Plank To Push-Up

  • Beginning in a high planking position (i.e. on your hands instead of your elbows), keep your arms directly beneath your shoulders and maintain core engagement.
  • One at a time, lift your arm and place your elbow down, ending in a traditional plank position.
  • Return your arms one at a time to the starting position and repeat.

9. Tricep Dips

  • Sitting on the edge of a bench, bend your knees at 90 degrees and have your feet firmly planted on the floor.
  • Gripping the bench with your hands on either side of your hips, push your glutes up and off the bench, and then lower your body 2-3 inches down as you bend your elbow whilst keeping them close to your body.
  • Then, slowly raise your body back to the starting position and repeat.

10. Dumbbell Punch

  • Standing with your feet shoulder-width apart, hold your dumbbells and keep your knees loose (slightly bent – not locked back).
  • Lift your arms and punch them straight out in front of you, alternating each and keeping the dumbbells at shoulder level as you do.
  • Avoid jerky movements by allowing your hips to naturally move with your body as to punch, and repeat sets for a timed period.
