Gyms are great, but they certainly aren’t necessary to get a great workout. If you don’t have access to a gym or are uncomfortable working out in public, you can still enjoy a quality workout from the comfort of your own home (or anywhere).

Exercises that use body weight are key. You can improve your strength and create resistance with the exercises below just using your body weight. Check out these three simple — yet effective — exercises to help get you started:

Bodyweight Squats – Place your feet shoulder-width apart and perform bodyweight squats. Slowly bend your knees and point your toes outward. Make sure your back is straight and your core is engaged. Repeat 6X in a row to complete one set.

Planks – Start in a push-up position, then lay your forearms flat on the floor with your elbows aligned below your shoulders. Make sure your body is straight and your core is engaged. Start by holding the position for at least 10 seconds (or longer if you can). Depending on your comfort level, repeat this exercise 3-5X.

Dips – Start by sitting on the edge of a chair and doing tricep dips. Slowly walk your feet forward while gripping the chair with both hands at your sides. Make sure your knees do not extend past your toes. Lower your body so that your elbows bend above you at a 90-degree angle. Repeat 6X in a row to complete one set.

Last, finish your strength training session with a quick cardio session (e.g., dancing, jump-roping, or a brisk walk around the block). The goal should be to get 150 minutes of moderate physical activity that includes at least two days of strength training per week.

Now that you know how to do the basics, you can start enjoying the benefits of exercise without spending a fortune on a gym membership or leaving your home!
