it doesn't really matter that much because exercise makes the muscle more sensitive to the stimulation of muscle protein synthesis through food intake but it does so for up to 24 to even 48 hours so if you do an exercise session today your response to breakfast tomorrow morning will be greater but also lunch tomorrow afternoon and also dinner tomorrow night and so after that you have your second exercise session so it's not about what should go first but it's a consistency of training and meals in between and the training will make your me more efficient in how they optimize muscle reconditioning
