Obviously not CT here so take the following with a grain of salt, but:
I would suggest sticking to this program with 100% compliance for a period of at least 3-4 months before trying to advance to another program. A couple of my friends (both beginners) had HUGE success on this program and are still running it ~6months later. Their body went from chubby, non-lifter to a much more athletic build.
Not only did their aesthetics improve substantially, but their lifts all went through the roof. Take advantage of those “noob gains” and don’t over complicate things.
Read into starting strength and buy into it 100%. Trust the system and do everything as written for 3-4 months straight. CT’s programs are great, but you really need to know not only the proper techniques but you need to know your body in terms of recovery and how much volume/intensity you’re able to get away with, specifically in a caloric deficit.
