How can I build muscle without heavy weights?

Building muscle without heavy weights is absolutely possible by focusing on bodyweight exercises, progressive overload, and proper form. Exercises like push-ups, pull-ups, squats, and lunges can be made more challenging by increasing reps, slowing down tempo, or adding resistance bands. Nutrition and recovery play a key role, so ensure you’re consuming enough protein and getting adequate rest. Consistency and variation in your training will steadily increase muscle strength and endurance, even without lifting heavy.
