Weighted vests are a great way to add resistance to your push up and build your muscles further. Strap the weighted vest on as tight as you can while still remaining comfortable. This way, you can prevent the vest from sagging and hindering your movements. Then do your normal push ups. You can purchase weighted vests from your local sporting goods store. This is a great way to add resistance that’s an alternative to wearing a weighted vest. Fill a backpack with books, bags of rice, or other heavy objects until the weight of the backpack is equal to or less than 20% of your body weight. Then do your normal push ups.  For example, if you weigh 120 pounds, then your backpack should weigh a maximum of 24 pounds. It’s important to keep the weight within 20% of your body weight in order to prevent overloading your spine, shoulders, and elbows. While you are doing your normal push up, ask a friend to place their hand on your upper back. Tell them to apply pressure on your back as you raise yourself up from the push up. Make sure your friend applies consistent pressure for each push up.
