Another idea would be to replace your traditional workouts with other more varied and fun, but equally physical activities. In this way, you will allow your body to stay active without even realising it.
Are you spending your holidays at the sea? Why not take the opportunity to learn to surf, meet new people on the beach volleyball court or go swimming in the waves? Not only will you get active, but you'll also come out with a killer tan (just remember to wear sunscreen).
In the mountains, you'll find yourself in a perfect playground for hiking. You can discover the satisfaction of seeing some of the most sublime scenery after a long walk during the day. Cycling can also be a great ally at these times. The wide open country roads will allow you to enjoy the fresh air without the exhaust fumes of the bus ahead of you in town.
Be curious, see what possibilities are available to you in the surrounding area and test it out. Maybe you'll even discover a new passion?
