The R's boss claimed that Taarabt is 'three stone overweight' in a recent press conference which prompted a passionate reaction from the Moroccan playmaker.
Taarabt, who spent part of last season on loan at AC Milan, believes QPR's training regime under Redknapp is not good enough and that the Loftus Road boss hardly ever leaves his office to watch his players.
"I am a professional - this is not about retaliation, this is about protecting my reputation," Taarabt told the Daily Mail.
"I played in that reserve game for 90 minutes (against Wolves last week) and if he didn't think I was running he could have taken me off. Maybe I didn't perform like I could because it was a reserve team game and I was protecting myself.
"He spends most of the time in his office but when he gets off the phone he comes down to watch for five or 10 minutes - he never takes a session," Taarabt further revealed.
"That's when he said he had it in mind to start me against Liverpool."
Taarabt added: "The training sessions aren't the same standard as Milan, or what I would expect under another manager.
"They are not as intense, the players aren't as motivated. It is the same as we used to do at Tottenham years ago. When we played West Ham he told the players 'you're not fit, you're not this, you're not that'.
"I said 'but the problem is we don't have any plan in the game, we don't know how to press as a team. It's not about just running around, you need to play with your brain'."
