You don't necessarily need access to workout equipment in order to build your muscles. These 7 exercises only use your body’s weight as a source of resistance. If you do enough sets and repetitions of these exercises, you can build all the muscle groups in your body without ever having to use weights. Push-ups The push-up is the ultimate bodyweight exercise because it works out multiple muscle groups at the same time. Push-ups can help you build muscles in your arms, shoulders, chest, abdomen, and even legs. Push-ups will improve your upper body muscle definition, strengthen your core muscles, and improve your whole body’s muscle density. In order to reap the maximum benefits from push-ups, you need to ensure that you do them correctly. When you get into the push-up position, you should ensure that your head, your neck, your hips and your legs are all in a straight line, and they remain so throughout the push-up. This will help ensure that all the muscle groups get the resistance that they need in order to develop. Dips Dips are mostly used to build the triceps, but they also work out the deltoids and the pectoral muscles. A narrow stance is good for the triceps while a wider stance is good for the pectorals.
