Bodyweight exercises can make you big and strong. While typically, bodyweight exercises are equated with higher rep schemes and endurance test – how many push ups can you do unbroken, for example – you can still adopt certain methodologies to enhance muscle growth and achieve hypertrophy without having to resort to weights.
One of the other advantages of bodyweight exercises is that they can be done almost any place, any time. The only thing you need for a bodyweight workout session is you. So, done right, resistance training that is purely based on bodyweight can maximize strength and size as well as equipment based training.
