All these workouts:
20-Minute Bodyweight Interval Workout
Legs & Butt Bodyweight Workout
30-Minute Bodyweight Movement Pyramid Workout
No-Rest Tabata Workout with Isometric Holds
Another great tip is to pack resistance bands with you when traveling–they hardly take up any space in a bag, are super light, and can help you spice it up if you’re sick of bodyweight workouts.
