Whether 100 reps is okay depends on your fitness goals and current level of fitness. For endurance training, doing 100 reps with light weights can be beneficial. However, for building muscle or strength, fewer reps with heavier weights are more effective. It's important to listen to your body and adjust the number of reps based on your specific goals and how your body responds to the workout. Always prioritize form and safety over sheer numbers to prevent injury.
