Fitness experts in Mexico and Spain stress beach walking boosts calories but strains joints

Walking on the beach, especially on dry, soft sand away from the water, requires greater effort and therefore increases calorie expenditure. Juan Antonio Martín, a personal trainer, explains that "la arena seca y blanda, que es la que está más alejada del agua, es la que más esfuerzo exige y por tanto la que más gasto calórico genera". The varied terrain of sand, water and open air also offers resistance training, mental benefits and a dynamic alternative to gym routines.

The same increased effort places additional load on the ankles, knees and lower back, raising the risk of joint discomfort or injury. Experts advise incorporating beach walking gradually, alternating between dry and wet sand, and paying attention to the body's signals to enjoy the fitness gains while minimizing strain.
