How to reduce Injuries when performing Dumbbell curls?
One of the biggest concerns is “Injuries”. Dumbbell Curls are likely to injure your Forearms. Some of the reasons you may injure your forearm, Lower back, elbows, wrist and traps when performing dumbbell curls are Bad Form/Techniques, Heavyweights and Overtraining.
- Bad Form/Techniques: You need to make sure that you focus on the correct muscle group when performing Dumbbell curls. You will see a lot of people performing the same exercise, but their form is slightly different to others. This is due to bad Form/Techniques. When performing dumbbell curls, you need to remove momentum and keep each rep nice and controlled. This means No swinging, curling up with the medium pace and slowly bringing it back to the starting position. This will result in no pressure or discomfort on your Lower back and traps.
- Heavy Weights: Lots of people in the gym like to compete “He curls 15 Kgs for 10 reps, I can do that too” This leads to injuries on your forearms and wrist. You will see people in the gym lifting heavy weights even though they are in pain and discomfort. This will also lead to bad form. Therefore, curls whatever weight is medium/heavy for you. For example, if you can easily do 10 kg dumbbell curls for 12 reps then move to 12 kg dumbbell curls and not jump to 18 kg. Remember, training is a long-term investment so you need to make sure that you can lift it without getting injured.
- Overtraining: Training too often can cause injuries to your muscle group and joints as you need to allow your muscle to repair. Give yourself some recovery time if you have discomfort, continued pain, or illness on your forearms. Take a few days off; Rest. Put some ice on your forearms as it will reduce the swelling and the pain. If the pain is still there, then seek advice from health professionals.
Injuries can be prevented by performing the workout correctly, doing the right amount of reps and set, lifting a weight that is too heavy for you and wearing the right protection wear. Make sure you keep your wrist and forearm protected as it’s required for all exercises which include push and pull.
How to improve my dumbbell curls?
This depends on what your goals are. You want to Increase Strengthen Biceps, Gaining Biceps Muscle Size, and Toning Biceps. All these goals will have a slightly different impact on Biceps.
- Strengthen Biceps: This is where you challenge the strength of your forearms and biceps. By performing heavy dumbbells and performing two – six sets of biceps workouts. With a heavyweight aim for 8 -10 reps at the same time try to keep your form as correct as possible. Due to heavy weight, you need to make sure you have enough rest time between each set. Rest time should be anywhere between 2 mins to 4 mins between each set. Additionally, try not to perform the same strength training for the consecutive day. Give your muscle some rest to recover.
- Gaining Muscle Size: Increase your biceps muscle. This is how Bodybuilders train. The aim for this is to have large and well-defined muscles (biceps). Get a dumbbell where the weight is medium/heavy and perform two – six sets of biceps workouts. Always ensure your form is correct when performing dumbbell curls. Make sure your rep range for each set is from 10-12 reps. Rest time should be anywhere from 30 – 120 seconds between each set. Make sure you perform Gaining Muscle Size training for the biceps once a week.
- Toning Biceps: There is a high number of women who choose this type of workout as it tones down the muscle without increasing its size. Use a weight which is light and perform two-four sets of biceps workouts. With the correct form perform 15 -20 reps as you will be focusing on muscle endurance. The more reps the more resistance. As the weight is lighter, your rest time should be shorter, anywhere from 15 – 30 seconds. You can perform this type of bicep training 2 times a week.
All these types of training will help you increase your biceps. However, that is not enough. You need to make sure you have enough rest to allow the muscle to grow. Having a good diet is important as it will increase the process.
