Tập luyện ab khỏa thân

Hi there, Adrienne! It's so good to see you today. Very nice of you to join me in working

out. So, we're going to be mostly focusing on our apps today, and who knows, maybe you'll

learn a few new things from me. But we may as well get right into it. So be sure to follow

along and definitely don't get distracted. So we're just going to start off by doing

some basic crunches, just as a warm-up. I'm trying to keep up with you.
