I AM TRYING TO GET BACK IN SHAPE, STARTING AGAIN FROM 0, OR BEGINNER. WHICH PROGRAM IS FOR ME?
The best choices for beginners would be Lockdown Protocol or Tactical Bodyweight. Both of these programs will build a solid foundation of strength and endurance to transition into a weightlifting program and kickstart you back into training.
If you do not have access to any equipment or can't perform one pull-up, then Lockdown Protocol is the best choice for you. If you have access to a pullup bar and can perform or want to build on your pull-ups, Tactical Bodyweight is the way to go.
