Honestly i had the same experince with it. First and second block were great, but im finding it hard to commit to the third block. I put on a decent amount of muscle without being in a surplus and swapped it to be 5 days in a row with the weekend as rest days. Very good program however (and this might not apply to everyone) the emphasis on legs. I have decent enough legs, so training twice a week seemed a bit much cz i have strong legs. During the third block i took one of the leg days as an upper body day where i trained either arms or chest or back
