Push ups are a versatile bodyweight exercise that strengthen the chest, shoulders, triceps, and core. Common mistakes include flaring elbows too wide and arching the lower back. Keep elbows at a 45-degree angle and maintain a straight line from head to heels. For beginners, start on knees or use an incline. Advanced variations include decline push-ups or adding a clap. Ensure full range of motion by lowering until elbows are at a 90-degree angle or less. Push-ups improve upper body strength and endurance, and can be adapted for any fitness level by adjusting reps, sets, or variations.
