Strategies to maintain fitness during travel include incorporating quick workout routines, staying active throughout the day, and searching for local fitness resources. Utilizing bodyweight exercises such as push-ups, squats, and planks can be effective for efficient workouts in limited spaces. Engaging in outdoor activities like walking, hiking, or exploring new areas can keep individuals active while enjoying their travels. Additionally, researching hotels with gyms or joining local fitness classes can provide opportunities to maintain regular exercise habits despite changes in schedule or environment.
