Why do my arms look smaller the day after a workout?

Muscle growth is facilitated by an anabolic or building-up process called hypertrophy. If your muscles are getting smaller, they are atrophying. Atrophy is a catabolic process that occurs if your training, diet or lifestyle is not sufficiently aligned with your goal of making your muscles bigger.

Why do my biceps get pumped so fast?

As you curl the weight, the individual fibers inside your biceps expand. This compresses the veins, taking blood out of the muscle. Because blood is being pumped into your biceps faster than it can leave (when you work out, there’s an increase in blood flow), the muscle becomes temporarily engorged with blood.

Why do my muscles feel bigger after a workout?

Why are my biceps not sore the next day?

Should you lift heavy for biceps?

“But to build bigger biceps and triceps you have to focus on perfect form, moving through a full range of motion and, crucially, never lifting too heavy. The key to adding arm size is to getting a good pump through lifting lighter for longer – and executing every rep as perfectly as possible.”

What is the pump feeling?

The pump is when your muscles swell up during your workout, which is caused from the excessive amount of blood going into the muscle and filling it up the same way you would fill up a water balloon. Your muscles get a very full, tight feeling and your skin becomes tighter because of this.
