number one How are you supposed to determine a max weight you can do for given amount of reps for every exercise?
I'll try and cut and past a chart that will help. You want to be able to complete the targeted number of reps (not fail before it). If you fail on the last rep of last, it OK (that's what I ideally try to do). Remember, you're doing 2 sets, so if the first set was too heavy, decrease some for next set. If it's still too heavy, reduce for that exercise next session. Same thing, only reverse, if it's too light.
am I supposed to go in the gym and determine maxes for every lift before i start the program?
The chart I'll post will give you a good ballpark, only it goes up to 12 reps, not 15.
Can i use a rought estimate or should this be exact?
"exact"?!? - this is more like throwing hand grenades than Rocket Science
number two If I am supposed to actually physically test myself, How am I supposed to determine a 10 rep max after completing my 15 rep phase.
Again - I'll try and cut-and-paste my chart. If it doesn't work I'll have to make a graphic, then post it.
If I finished my workout on friday When am i supposed to figure out maxes when i'm expected to perform my next workout on Monday
Again - see above^
number three I was under the impression that u were supposed to perform the same exercises throughout the program--using a progressive load principle of adding weight each workout building up to your max intensity workout at the end of the 2 week period.
This is what I do. You can mixup exercises for each new HST cycle. But there are some excercises I "always" perform - "slight" incline bench and squats, then either bent-over rows or rack deadlifts.
the HST program below illustrates this workout design.
**broken link removed**
however, this sample workout on the last page of HST illustrates shows the person switching up exercises from workout to workout. How are u supposed to progressively load if you are using different exercise or more specifically know how much to increment the weight based on the other exercise?
That's why I use the same exercises. I got that the benefits are the rep/set/#time @ week not mixing up exercises.
