When you have time training, it is likely that at some point you feel stuck and do not see the results you want. This can happen with any muscle group, but it is a very common phenomenon when we train our biceps.
If this happens to you, it is necessary to change the stimulus that is generated in the muscle. For this, there are two options: train with more weight and repetitions; or simply change the exercises. Following this idea, there are some unusual, but very effective exercises for the biceps to break the stagnation of the muscle.

Landmine Reverse Curl
This is a very interesting exercise. To do it, you have to use a reverse grip, which is not widely used in biceps training because it allows you to lift less weight. However, it allows you to activate different areas or angles of the biceps. You can compensate for the reduced weight with more reps.
Hammer Curl 6/6/12
To finish your training, you can use doing several repetitions of Hammer Curl with a variation. You must first start with a series of 6 repetitions while sitting and, without rest, perform a series of 6 repetitions while standing. The superset ends with 12 reps of the exercise using a training band.
Triple threat
With this exercise, we try to stimulate different areas of the biceps. It consists of training the muscle first by placing the elbows in front of the body, then close to the body, and finally behind it. This is a modality we are not used to, so it adds a level of difficulty that will help you get out of the stalemate.
Kettlebell exercises
To finish, we want to recommend some kettlebell exercises. These tools modify your grip and completely change the feel of your biceps. The weight distribution is different, and therefore the muscle tension increases.
