Working out after IVF

I'm 5w2d and was told after my positive beta to limit workouts to brisk walks until I hear otherwise. Is this just normal protocol after ivf? Not complaining about not being able to workout as I would have gladly stood on my head for a week straight if someone told me that could guarantee a pregnancy ?, just curious!!
