It's almost the end of June, only 16 days of exercise. I have been working overtime these days, and I get off work at 5 am-12 am-at 3 am, everyone will be exhausted!

Look in the mirror, don't talk about muscles, I feel like I'm losing meat.

I finally got off work on time yesterday and went home to exercise immediately:

Aerobic: 30 minutes of sweaty boxing practice, the one in red, the favorite one, did not jump much (after all, squatting? ) and you can practice to the upper body.

Anaerobic: 10 minute abdominal muscle killer? 10 minute lower abdominal training
