All workouts come with videos explaining set-up and execution for each exercise.
If you're new to a program, take a moment before your workout to watch the videos going into detail on each exercise. That way you'll get the most out of your time at the gym.
On the website, you can access 170 videos explaining every exercise in detail on HypertrophyCoachTV in the menu bar.
To access the Exercise Library on the app, click the TV icon on the bottom right corner.
If you still have questions, ask in the forum either on the website or the app.
