Use these everyday objects to exercise without having to leave the dorm.

As a biology student who's living on a budget, Garry Y. Itkin spends a lot of his time doing his fitness exercises in his dorm. You might be surprised that you have mostly everything you need at home to help you through your fitness plans so you can spare yourself from investing in gym equipment.

Here are some examples:

1. Stool

A stool is quite versatile as an exercise aid. You can certainly do box jumps with it. You can also do some inclined pushups with your stool, which can both give you less or more resistance, depending on where you place your feet. You can practice lateral high jumps with a high enough stool, which is awesome for cardio, says Garry Y. Itkin. Once you realize how many things you can do with a stool, you'll be so amazed.

2. Books

When you're in school, it's all about hitting the books. Since you have them around at the dorm anyway, why not use them for exercise, too? Books are great for adding resistance to your normal stationary exercises. For example, a thick enough book can act as a dumbbell that can target your biceps and triceps. You may even lay a book flat on your chest as you do crunches for that extra bit of challenge.

3. Detergent bottles

Detergent bottles are also great to have, simply because whatever you can do in kettlebell exercises, you can do with it, too. As Garry Y. Itkin suggests, deadlifts can even be more amazing when you use a detergent bottle or even two. As you hold a detergent bottle in each hand, you can climb up your building's stairs and work up your upper body for that added strength that you can surely use.
