I have met Gary Frank multiple times and he is definitely an incredible guy. You wanna know how strong he is go and shake his hand. It feels like holding a piece of steel.
Yeah thats absolutely normal. Naturally you can only recover from so much. So adding those 2 exercises could have affected your recovery. Now all 3 are trying to grow but its a very rare person that can get all 3 big lifts to improve at the same time. I have been power-lifting for 12 years...
What i usually concern myself with is getting good nutrition. I try to eat plenty of fruit vegetables and have various different protein sources in my diet. I do a good job when healthy of getting about 500 grams of protein a day.
