TOP 5 ARM EXERCISES FOR BEGINNERS

Published: 31/12/2025 | By: David van Wetherill

A new year brings fresh motivation, and for many that means getting back into the gym – or stepping in for the first time. If you’re starting your fitness journey, training your arms is one of the easiest and most motivating places to begin. Seeing your strength build week by week is a real confidence boost. In this piece, Sports Direct ambassador David Van Wetherill shares his go-to arm exercises to help you get started.

When I first started working out, arm day was my comfort zone. It goes without saying that, in comparison to my legs, they have always been my strength. Not only that, but the movements felt straightforward, the progress came quickly, and it taught me fundamentals I still rely on today: control, tempo, joint safety and stability, and how to move with intention instead of just “lifting something heavy”.

It has become critical to my functionality as an adaptive athlete on crutches – not just for performance, but for life. We must work on our weaknesses, but we certainly must maximise our strengths.

This guide walks you through the arm exercises that helped me most as a beginner – what worked, what didn’t, the mistakes I made early on, and what I wish someone had told me sooner.

WHY TRAINING YOUR ARMS MATTERS

A lot of beginners think arm training is just about aesthetics. Sure, stronger arms may look good to some, but there’s much more to it. Training for strength, stability and performance is the primary goal for me.

1. Everyday Functionality

Lifting bags, picking up washing, groceries – you name it – pushing and pulling… it all requires arm strength.

2. Better Overall Training Performance

Stronger biceps, triceps and shoulders help you press better, pull better, stabilise better, and reduce compensations in major lifts.

3. Injury Prevention

Weak arms can overload the wrists, elbows and shoulders during larger compound movements. Strengthening the smaller muscles protects the bigger ones.

4. Confidence and Early Wins

As a beginner, arm exercises offer some of the fastest strength and muscle gains, which definitely helped my confidence to stay motivated.

TYPES OF EXERCISES: WHAT TO FOCUS ON AND WHY THEY MATTER

Below are five of my most beginner-friendly arm exercises. They work the muscles differently and help build a strong, balanced foundation.

1. Triceps Dips

A highly effective compound exercise that primarily targets the triceps, while also engaging the shoulders and chest. You can do them at home using a stable chair or bench.

How to Do Them

• Sit on the edge of a sturdy chair, bench or step and grip the edge next to your hips.
• Slide forward so your hips are off the edge and support your weight with your arms.
• Lower yourself by bending your elbows until they’re about 45–90°, then press back up.

Why They Matter

Triceps dips are one of the most effective exercises for activating the triceps brachii – the main muscle responsible for elbow extension – while also recruiting stabiliser muscles in the shoulders and core.

Beginner Tips

• Keep shoulders down and away from your ears to protect the shoulder capsule.
• Don’t go too low if you start to feel shoulder strain – control the range of motion.
• Keep your feet flat and legs bent to make the movement more joint-friendly at first.

Reps, Sets & Rest

• 3–4 sets of 10–12 reps

60–90 seconds rest

2. Dumbbell Bicep Curls

The classic biceps-building exercise. Simple, effective, and perfect for those starting out.

How to Do Them

• Stand or sit tall with dumbbells at your sides.
• Keep elbows close to your torso.
• Curl the weights up without swinging, then lower with control.

Why They Work

Curls isolate the bicep and teach you how to control elbow movement, which is crucial for all pulling exercises.

Beginner Tips

• Choose a weight you can lift for slow, clean reps.
• Keep shoulders relaxed and don’t shrug.
• Avoid leaning back or using momentum.

Reps, Sets & Rest

• 3–4 sets of 10–12 reps

60–90 seconds rest

3. Diamond Push-Ups

A bodyweight pushing variation that places emphasis on the triceps, while also engaging the chest, shoulders and core.

How to Do Them

• Start in a plank position and form a diamond shape with your hands by touching your thumbs and index fingers together directly under your chest.
• Lower your chest towards the diamond shape, keeping your core braced.
• Press back up to the start position with control.

Why They’re Important

Diamond push-ups target the triceps more than standard push-ups by narrowing hand positioning, and they also improve core and shoulder stability.

Beginner Tips

• If full diamond push-ups are too hard, start on your knees or with hands elevated on a step or bench.
• Keep elbows close to your body to maximise triceps activation.

Reps, Sets & Rest

• 3–4 sets of 8–12 reps

60–90 seconds rest

4. Tricep Kickbacks

A simple movement that isolates the triceps – the muscle responsible for arm extension and roughly two-thirds of your upper arm size.

How to Do Them

• Hinge forward with a near-flat back.
• Hold a dumbbell with your elbow bent at 90°.
• Extend your arm straight back, squeeze, then return to 90°.

Why They Matter

Kickbacks improve elbow stability and strengthen the back of the arm, complementing pressing movements.

Beginner Tips

• Only the forearm should move – keep the upper arm still.
• Choose a light weight to feel your triceps, not your shoulders.
• Keep your wrist neutral.

Reps, Sets & Rest

• 3–4 sets of 12–15 reps

60 seconds rest

5. Hammer Curls

Hammer curls train both the biceps and the brachialis – a deeper muscle that adds thickness to the upper arm.

How to Do Them

• Hold dumbbells with palms facing each other.
• Curl upward keeping elbows close.
• Lower with control.

Why They’re Important

They mimic natural grip patterns and help strengthen your forearms and grip.

Beginner Tips

• Don’t grip too tightly – over-squeezing fatigues the forearms.
• Keep wrists straight.
• Move slowly to avoid swinging.

Reps, Sets & Rest

• 3–4 sets of 10–12 reps
• 60–90 seconds rest

SAMPLE BEGINNER ARM WORKOUT

A manageable session 2–3 times per week with at least one rest day in between.

Warm-Up (3–4 minutes)

• Light band pull-aparts or shoulder rolls
• Gentle arm swings and mobility work

Main Workout

• Dumbbell Bicep Curls: 3 x 10–12 reps
• Triceps Dips: 3 x 10–12 reps
• Diamond Push-Ups: 3 x 8–12 reps
• Hammer Curls: 3 x 10–12 reps
• Tricep Kickbacks: 3 x 12–15 reps

Rest

• 60–90 seconds between sets
• 2 minutes between exercises

TIPS TO AVOID ARM INJURIES

1. Warm Up Properly: Cold muscles are more prone to strain. Spend a few minutes warming up your arms with light movements like arm swings, light curls, and band pull-aparts to get blood flowing.
2. Keep Control Throughout Each Rep: Avoid letting your arms “flail” or move too fast. Controlled movements protect your biceps, triceps and forearms and help you build strength more effectively.
3. Choose a Manageable Weight: If you can’t complete a full set with good form, the weight is too heavy. Picking a load you can control through the full range of motion reduces the risk of strains and overuse injuries.
4. Prioritise Form When Fatigued: Arm injuries often happen when you’re tired and losing control. When your technique starts to slip or you feel sharp or unusual pain, stop – mistakes and injuries happen in the final reps.
5. Balance Your Pulls and PressesStrengthen both pushing (triceps) and pulling (biceps and forearm) muscles evenly. Overdeveloping one side without the other can lead to imbalances and elbow or forearm pain. Including variations like hammer curls and triceps dips helps maintain balance.

STRONG ARMS ARE A BEGINNING, NOT THE END

Building arm strength is rewarding, motivating and empowering – not just physically, but mentally. These exercises offer a foundation you can build on for months and years to come. Remember:

• Start light.
• Move intentionally.
• Focus on the process, not perfection.

Consistency wins every time.
