This one is called an AMRAP: As Many Rounds As Possible in a certain amount of time. This one will be a 20 Minute AMRAP. Be sure to complete a good 10 minute warm up and a few minutes of stretching before doing this workout.
Find a location where you can complete 15 walking lunges in a straight line.
1 Round is:
15 walking lunges
8 Chest to Deck Burpees
15 walking lunges (back to where you started)
8 push ups
Just keep lunging back and forth and completing the burpees and push ups at either side. To kick it up a notch you could add 8 to 10 lb weights and carry them overhead for the lunges. (lock out your elbows and hold the weights directly above your shoulders.)
This workout could be done anywhere . . . on vacation, at home, on a business trip, in a small place, in a park, at the beach . . . . anywhere! Regardless, it will be effective.
Let me know how it goes.
