Hey guys, I'm starting my HST program tomorrow (almost done with 9 days SD omg) and I have a couple of questions.
I have not been lifting really seriously until now and I find some exercises have low weights (incline bench, shoulder press). Is my lack of strength gonna have a negative impact on my muscle size growth? I was told that HST is the last program you wanna do if you lack strength. Is that true? Should I do something else? If so I'm really mad because I just lost 9 days on SD...
I could not test my Barbell Upright Row's RMs since I added the exercise while I was in my SD. I guessed 35lbs as my 15RM. Based on my other weights, do you think it sounds fair?
I've never done Calf Raises before and couldn't test my RMs at my previous gym. What would be a good estimate knowing my calves are fairly strong?
Any opinion and/or critiques are welcome too.
