After coming across an article on T-Nation about HST I was intrigued by the premise of the program, and a little Googling lead me to Brian Haycock's Official HST site. The preceding year I was doing a reverse pyramid push/pull routine. Each main muscle group got three exercises comprised of three sets each (4-5 reps set 1, 6-7 set 2, and 7-10 set 3). By the end of a workout (typically 60 mins) my muscles were thoroughly pumped and I would have that good soreness feeling for 2-4 days post workout. I was hitting the gym 12-14 days per month and did chest/tris day 1, lats/bis day 2, shoulders/traps/abs day 3, and legs on day 4. But I had plateaued, and was no longer getting any real gains in size/muscle growth towards the end of the year. After reading the HST eBook and associated articles, plus perusing this forum, I crafted a program based on the HST model and started. So far I'm 4 weeks in having just finished my two weeks of 15s and two weeks of 10s, After establishing my 5/10/15 rep maxes I set up my routine to increase weight for larger muscle groups (quads, pecs, etc.) by 10 lbs each workout, and smaller muscles (biceps, triceps, etc.) by 5 lbs each workout building up to my max reps on the final workout of each cycle. With the HST program since muscle groups only get 1, maybe 2 at most, sets per workout session I never get a good pump (heck, I don't even get a pump at all). And I'm never sore the day after a workout. Other than the last two days of each cycle, the preceding days the weight just isn't a challenge and feels like a light weight warm-up set. This has me wondering if I'm doing something wrong or if I will see any gains from this program. I'm making sure I'm doing really good form, and only resting 30-45 seconds between sets (at least for the 15s and 10s, will rest longer during the 5s). Here are the exercises and number of sets I'm doing: Day 1 Squat x 2 Bench press x 2 Leg curl x 1 Chin ups x 2 Seated Military Press x 2 Decline sit ups x 1 Wide EZ bar curl x 1 Calf Presses x 2 Skull Crushers x 1 Day 2 Leg Press x 2 Decline Press x 2 Leg curl x 1 Bent Over Rows x 2 Shoulder Shrugs x 2 Decline sit ups x 1 Wide EZ bar curl x 1 Calf Presses x 2 Skull Crushers x 1 Am I just not supposed to get a pump during a workout, or soreness a day after a workout, with HST? Am I doing this wrong? Any advice/feedback/tips are appreciated.
