|If you want to try something new, but feel that this is a bit over the top, why don't you try an alternate workout regimen to escape the daily grind?|
What's better sequential or alternating?
I see, you are scratching your head... well, maybe you'll feel enlightened, after having read what Hamid Arazi, Siavash Rahmati and Samira Zaheri from the Department of Exercise Physiology, Faculty of Sport Sciences at the University of Guilan in Rasht, Iran have found in their most recent study on the effectiveness of 10 weeks of alternating vs. sequential push and pull training of the large and small muscle groups in 24 healthy male athletes (age 22y, BF% 14, weight 72kg) with a history of at least 3-6 months of weight training (Arazi. 2013).
The actual training protocol, the two groups followed was virtually identical except for the exercise order, of course:
- frequency: 3x /week
- rest: 48h between workouts; 2 min between upper, 3 min between lower body ex.
- duration: 70-80min per workout (20 minutes warm-up + cool down)
- progression: linear, every two weeks - 60%1RM\12reps < 65%1RM\12reps < 70%1RM\10reps < 75%1RM\10reps < 80%1RM\8reps
- exercise selection: 3 sets of leg extensions, leg curls, rows and bench presses for the major and 3 sets of bicep curls and triceps extensions for the smaller muscle groups
- push vs. pull: leg extension, chest press, and triceps extension are push exercises; leg curl, biceps curl and rowing are pull exercises
- sequential training: "Sequence means each exercise is performed for 3 sets (with intervals of rest) and then next exercise starts moving again." (Arazi. 2013)
- alternating training: "Each session was conducted by leg extension (1 set) and leg curl (1 set). The alternative means the opposing muscles (requires push and pull) that were trained alternatively ." (Arazi. 2013)

Still the overall message the researchers formulate in the conclusion to their paper, where it says that it would be "suggested to use the opposing exercises for strengthening agonist –antagonist exercises" (Arazi. 2013) is not totally beside the point. Nevertheless,I'd expect better hypertrophy effects if you reduce the inter-set rest times from 2 minutes to 60s and from 3 minutes to 90s for the large and small muscle groups, respectively.
Blueprint for a 2-day alternating muscle split to be trained twice a week: Day 1: 4x6-8 bench presses / pull-ups, 3x8-10 military press / your favorite version of rows, 3x12 biceps curls / nose breakers; Day 2: 4x6-8 squats / stiff legged deadlifts, 3x8-10 bent over lateral / front raises, 3x15 leg extensions / hamstring curls; optional 5 min ab training on day 1 and 5 min calve training on day 2; inter-set rest 90s for complex, 60s for isolation exercises.Bottom line: While the study at hand certainly doesn't provide a conclusive answer to the question whether alternate or sequential training is the way to go for strength trainings, my personal experience is that alternating between exercises for antagonistic muscle groups as in a chest / lat, biceps / triceps, front delts / upper back, and quads / hams + glutes 4- or 2-day split with relatively short inter-set rest periods (90s for larger, and 60s for smaller muscle groups) can be more than just a diversion from the daily grind at the gym.
You can be in and out of the gym in <40 min and still lift a pretty decent amount of weight; and that, at a lower risk of CNS burnout than with a classic super-set training, where you would not rest between the push and pull movements, at all. The latter allows for a relatively high training frequency, but I would still take a day off between workouts, unless you are trying to cut weight at all costs. In that case, a fast paced training split build around the concept of alternating back and forth between exercises for agonist and antagonist can actually be worth way more than hours of classic "cardio" training or HIIT training. Just don't overdo it! While the individual muscles may still get enough rest, any increase in workout density will also increase the load on the central nervous system.
