On my recent trip I took 10 minutes after my run to do this quick strength circuit in the hotel fitness center. I walked in there without a plan and this is what happened. Next time you only have a few minutes to spare, grab some dumbbells and get moving.
Do 10-15 reps of each exercise (go until the last 2-3 reps are hard) and end the circuit with a 60 second plank.
Squats (with or without weights)
Step-ups (with or without weights)
Repeat entire circuit backwards starting with step-ups then squats, all the way back to bicep curls. End the entire circuit with a 60 second plank.
If you do this workout, let me know what you think!
