She’s started a new weight lifting program for her arms where she cycles quickly through various dumbbell exercises for a few minutes before resting and repeating later. She asks you to help her understand what’s happening in her muscle cells during and after those workouts.

Explanation / Answer

ANS) After the wieght training exercise done by her friend, her friend's body will start utilizing ATP stored in the body for energy and so will require huge amounts of oxygen to make those ATPs for boosting energy in the body. This further will lead to pumping more of blood into the muscles for retrieving those extra O2. Without enough oxygen, lactic corrosive starts taking place and is usually removed out of the body within 60 minutes of workout. Hence, her biceps will start growing bigger and stronger.
