The knee push-up is a modified version of the traditional push-up, making it easier for beginners or those with limited upper body strength. To perform a knee push-up, start by kneeling on the floor with your knees together and your hands placed slightly wider than shoulder-width apart. Lower your body towards the ground by bending your elbows, keeping your back straight, and then push back up to the starting position. This exercise primarily targets the chest, shoulders, and triceps, helping to build strength and stability. Knee push-ups are a great way to develop the necessary muscles for full push-ups, making them an excellent addition to any fitness routine.
