There is no specific number of repetitions that is considered ideal for increasing muscle size and strength. It will vary depending on individual factors such as fitness level, goals, and type of exercise being performed. In general, a good starting point for building muscle is to aim for 8-12 repetitions per set, using a weight that is challenging but allows for proper form. It is also important to progressively increase the weight and/or repetitions over time to continue seeing progress. It is recommended for beginners to start with lighter weights and higher repetitions to build a strong foundation before increasing the weight.
