Why Won’t My Arms Get Thinner?

Poor Nutrition

If your diet is low in protein, you’ll struggle to build muscle mass, even if you hit the gym regularly. Unfortunately, this means your arms will stay relatively flabby, no matter how many crunches you do. Many people try to slim down their arms with a low-fat, high-carbohydrate diet. This is a bad idea, as it can lead to you having low energy levels and feeling lethargic, meaning you won’t be able to exercise regularly. You need to consume high-protein foods, such as fish, chicken, eggs, and beans, to ensure you have the energy to hit the gym. Just by adding a few extra protein-rich meals to your diet, you may notice your arms slim down.


If you have genes that promote a higher ratio of fat to muscle, you’re more likely to have thicker arms compared to people with genes that promote a higher ratio of muscle to fat. However, don’t let your genes hold you back! You can still make your arms slimmer through a healthy diet and exercise routine. If you find your body tends towards a higher ratio of fat, you might want to consider a low-carbohydrate diet to help you lose weight.

Lack of Exercise

Without exercise, you can’t expect to slim down your arms. This doesn’t mean you need to hit the gym five times a week, either. You can slim down your arms through simple movements, like push-ups and crunches. Ideally, you want to do 10 different exercises for your upper arms and 10 for your lower arms. Not only will these exercises make your arms look better, they’ll also protect you against injury. If you’re a desk worker, you’re particularly at risk of developing upper-arm pain known as wings. Exercise can help prevent this, as well as many other health conditions linked to having thicker arms. Even if you already hit the gym regularly, you might be doing the wrong exercises. Research shows that the best exercises for slimming down your arms are bench press, dumbbell overhead press, and bent-over row.

Too Much Stress

If you’re under a lot of pressure at work or at home, your body may be unable to process all the excess weight. This means it’ll be stored in your arms, making them thicker. Slowing down and taking time for yourself can help you manage stress levels, so you don’t put on weight on your arms. You can also try yoga, which is a great way to relieve stress and meditation.

Sleep Deprivation

You may think that your arms aren’t affected by sleep deprivation, but it is actually one of the most common reasons why your arms won’t get thinner. Sleep deprivation can cause many health issues, including weight gain. Many people don’t realize that their lack of sleep is actually causing them to gain weight. You can try to combat this by making sure you’re getting enough sleep. If you’re having trouble sleeping, you can read our article on how to fall asleep faster.

Some people prefer working out in the morning, while others like to exercise later in the day.

Improving Sleep Quality

You should also try to go to bed at the same time each night, as this will help you fall asleep faster. You can also try to avoid stimulants before bed, such as coffee, energy drinks, and certain teas.

How To Work Out Your Arms Effectively?

  • If you’re struggling to get your arms slimmer, you may want to try adjusting the way you work out. Make sure to incorporate compound exercises, which target multiple muscles at once. Squats, deadlifts, and barbell rows are all great exercises that work multiple muscles including your arms.
  •  You should also try to avoid doing the same old exercises every day. Doing the same exercises every day and not challenging your muscles to grow can actually lead to your muscles becoming weaker over time.
  •  You should be mixing up your exercises and trying different variations every few weeks to keep your muscles on their toes and growing. 
  • You should also try to switch up the amount of weight you lift every couple of weeks to keep your muscles growing and avoid plateauing.
  •  Your muscles only start to grow when they’re challenged and are pushed to their max. If you’re lifting too light of weights, you’re not challenging your muscles and they won’t grow.

How To Make Sure You’re Getting Enough Rest?

  1. Make sure to get at least seven hours of sleep each night to keep your body and mind healthy and energized. If you are having trouble sleeping, try taking a warm bath with Epsom salts, reading, or meditating.
