The 12 best arm workouts to tone your muscles at home

• The best arm workouts target several major muscles at once.
• Tricep dips, push-ups, planks, and burpees will tone your arms and don't require weights.
• Exercise your upper body two to three times a week on non-consecutive days.

Exercising your arm muscles not only makes them more toned and buff, but also benefits your health because it helps to build muscle, burn fat, and strengthen joints and bones.

Here's everything you need to know about strengthening your arm muscles and which exercises are recommended by physical therapists and personal trainers.

Understanding arm muscles

Your arm is made of 24 different muscles, says Katherine Millis, a certified physical therapist and owner of Excelerate Physical Therapy. Of those muscles, they can be divided into two categories: the upper arm and the lower arm.

The upper arm muscles are those above your elbow and include your:

• Biceps, which help bend your arm
• Triceps, which help straighten your arm
• Deltoids, which help raise your arm overhead

Meanwhile, your lower arm consists of the muscles under your elbow, also known as your forearm. This region consists of 20 muscles which can be categorized as either:

• Flexor muscles help with bending movements like flexing your bicep.
• Extensor muscles help with movements away from your body like straightening your arm to grab something.

Here are 12 at-home arm workouts, recommended by Audrey Springer, a personal trainer and owner of Audrey Bowman Fitness. These exercises should be done two to three times per week on non-consecutive days. Complete three sets of each.

Insider's takeaway

There are several arm muscles in your upper and lower arm that help you perform movements like bending, extending, and waving.

For best results, strength train your arms two to three times per week on non-consecutive days. For example, you could strength train on Monday, Wednesday, and Friday each week.

If you are new to strength training, start by working out with a personal trainer or, if you're injured, a physical therapist to help you reach your fitness goals safely, Millis says.
