Jeff Cavaliere is a physical therapist and strength coach who has worked with professional athletes. His channel focuses on training correctly - not just getting bigger or faster, but moving well and staying injury free. He uses an anatomy model in many of his videos to show you exactly what's happening inside your body when you perform an exercise correctly versus incorrectly. That visual instruction is something most fitness channels don't offer and it makes a real difference in understanding what you're doing and why.

If you've ever felt like you were training hard but not seeing results, the answer is usually in the kitchen and Thomas will show you exactly what to fix.
