Bodyweight Travel Workout

Ever been on a business trip or vacation where you wanted to work out, but didn't have a gym or any equipment available? Or you come across those terrible hotel gym cheap-o kettlebells and you can't bring yourself to use them...

Never fear -- as long as you have a working, healthy body, you have all you need to get a great workout in! Sometimes sticking to the basics and going for additional volume is all you need to get your body sweating and feeling ready for the day. 

The workout shouldn't take longer than 30 minutes. Complete 5 rounds of the following, resting as needed between sets:
Side lunge 20 reps per leg
Push up 20 reps
Squat 20 reps
Reverse lunge 20 reps per leg
