How often to work your abs
The abdominal muscles, also known as the "core," are a group of muscles that are responsible for providing stability and support for the spine and pelvis. These muscles are designed to handle a lot of stress and are able to recover quickly, which is why it is generally considered safe to work them out every day. However, it's important to note that working out your abs every day should not be the only form of exercise in your routine.
When it comes to abdominal exercises, it's important to vary your routine to target all the different muscles in the core. This can include exercises such as crunches, planks, Russian twists, leg raises, and more. Another thing to consider is the intensity of your workout.
Listen to your gut, and train it hard.
