Incorporating a total body exercise, a back exercise, and a chest exercise in a first resistance training session is optimal because this approach promotes a balanced development of major muscle groups and ensures a comprehensive workout for new clients.

Total body exercises, such as squats or deadlifts, engage multiple muscle groups simultaneously, promoting functional movements and enhancing overall strength and coordination. Including a back exercise, like rows or pull-ups, is essential as it helps strengthen the posterior chain and counterbalances the muscles worked in chest exercises, preventing muscular imbalances and reducing the risk of injuries.

Additionally, a chest exercise is crucial for developing upper body strength and stability. By diversifying the session to include these key components—full body engagement, back strength, and chest development—clients are more likely to see improvements in their overall fitness and are more motivated by experiencing effective and varied movements.

The other options tend to focus on either a narrower selection of muscle groups or specific training styles that may not provide adequate overall stimulus for a beginner, leading to possible imbalances or lack of engagement in the workout.
