Sounds like you are over training. I am not sure what even do after 45minutes there to be honest. You don’t grow in the gym and not really even in the kitchen. You grow when you’re resting. The whole point of working out is to cause micro trauma which causes the muscle to be first broke down and then repair just a bit stronger than before.

My thought is, try dropping some volume and even days. Focus on rest and recovery and make your workouts super focused and intense but have the amount of time.
