Even if you have a top-model silhouette, you still need to go to the gym. You should do that if not for improving your figure but for keeping you fit and more important for your health.
If you would ask me the most important characteristics to search for when buying a workout bag, those would be:
– the size – it is important to have the proper size so all your gym equipment should fit in
– should have enough pockets
– comfort – it should be ergonomic and fit your body
