What the Country's Top Trainers Say Are Their Fitness Must Haves

Simone De La Rue, Body by Simone

Gym bag essentials: I carry a towel, change of workout clothes, iPhone charger, some snacks, almonds, crackers, and water.

Go-to workout equipment: I am currently obsessed with the sliding disc. They are so versatile. You can use them for a great core workout, lower body, and also upper body.

Pre- and post-workout snack: One hour before, I have protein and a carb, and one hour after, a protein. This can range from a protein shake to a boiled egg to grain free granola with almond milk or nut thin crackers and hummus.
