Let's not fool ourselves: Advertising claims like "Get your beach body in 3 weeks" are, well, advertising claims. In the end, it's all about continuity - 49 weeks of continuity have a greater effect than 3 weeks.
But hardly anyone achieves such a long phase of high continuity. Often life interferes and interrupts well running phases. Happens to all of us. Success in training is achieved by those who manage to get back into it again and again. And then 3 weeks can be an initial ignition!
A very good possibility to re-start or to put the finishing touches is a fresh Coaching at Unifit. New stimulus, more fun, the good feeling of keeping the ball rolling and leaving nothing to chance!
