The basic premise is that you see how many total reps you can perform (called your "PR" or "personal record") for two antagonistic exercises in 15 minutes using a 10RM weight. Then you get to choose the details (sets, reps, rest periods, etc.) for yourself. Workout by workout, you attempt to beat your PR's, ensuring gradually increased training density (hence, the name of the system). As you become capable of performing more and more work in the same period of time, your muscles are forced to adapt by growing bigger and stronger. As a connoisseur of systems, I loved the elegance of this concept. It allowed the end-user to use the system as he or she needed...it could be "plugged in" to existing training templates (such as the Westside barbell training split for example), or it could be used as a stand-alone training system – your choice. Unfortunately, although I was providing a highly effective tool, I perhaps wasn't providing enough structure. Or at least, not enough structure to satisfy people's curiosity. Here then, are 10 of the most common questions I receive about the EDT system, along with my answers and explanation. PR is short for "personal record." In EDT parlance, it specifically refers to the total amount of reps you're able to perform for two antagonistic or opposing exercises within a strictly-timed 15-minute time frame (read: PR Zone). It's been said that "success leaves clues," and in weight training, PR's are the clues left behind by improved fitness levels: eclipsing your current PR is concrete evidence that your muscles are growing bigger and stronger. This is user-friendly scientific method in action: we've held all other variables constant (duration and load, specifically) while we isolate the experimental variable: performance. EDT workouts require you to have uninterrupted access to two pieces of exercise equipment for an entire 15-minute PR Zone. In crowded gym environments, this can sometimes be challenging. But the solution is actually quite simple: as long as at least one of your antagonistic exercises is performed with a barbell or dumbbells, all you've got to do is carry the bar or dumbbells to your second station, which allows you to control access to that station for your PR Zone. Sure. Before you try EDT, you're likely to assume that 15 minutes is insufficient. AFTER you experience EDT, you start asking questions like this one. So sure, at least initially, 10-minute PR Zones are fine. "True" antagonistic pairings are fairly easy to figure out: elbow extension/elbow flexion (triceps/biceps)...push/press (e.g., bench press/row)...hip abduction/hip adduction, etc. The less obvious applications involve full-body moves (such as squats, pulls, etc.) and single-limb drills such as pistols, bent presses, and so forth. So here's how I handle these applications: For full-body lifts, there are two "best" options. This first is to perform the full-body lift first, using more traditional training parameters (5x5, 3x3, etc.), and then use EDT for auxiliary or "assistance" lifts. The second option that works very well is to pair two full-body lifts that have minimal overlap in terms of muscular topography: bench presses and front squats for example. Or rows and push presses. I also like to pair any type of squat or pull with a vertical pulling movement (such as chins or pulldowns) because the overhead pulling tends to decompress the spine in between the pulls or squats, which have a compressive effect on the spine. Here are some antagonistic pairings that have stood the test of time over the past 5 years of experimentation: Upper Body Bench Press/Chins Low Cable Row/Barbell Military Press Lat Pulldown/Triceps Pushdown Close-Grip Bench Press/Bent Rows Standing Barbell Curl/Lying Dumbbell Triceps Extension Floor Press/Reverse-Grip Cleans Push-Up/Pull-Up Lateral Raise/Cable Arm Adduction Straight-Arm Pulldown/Plate Raise Lower Body Leg Extension/Leg Curl Front Squat/Back Extension Seated Calf Raise/Tibealis Curl Hip Abduction/Hip Adduction Full Body Back Squat/Chins Front Squat/Dips Deadlift/Floor Press Overhead Squat/Clean Pull Muscle-Up/Power Clean Back Extension/Ball Crunch The "20/5 Rule" applies to reps performed for both exercises in a PR Zone. See question #4 above. The overriding principle is fatigue management. Appreciating this, you should have no problem determining effective pairings for yourself using any type of full body lifts. Using strongman lifts as an example, a great pairing is the farmer's walk with a thick-rope row. The possibilities are almost endless. Sort of. I hate people to get too wrapped up in looking for an "ideal" number of reps, but since I know they do, I'll provide some suggestions. GENERALLY, I like people to hit about 60-70 reps in a PR Zone on the first go-around. This means 60-70 reps on both exercises. Yes. EDT is designed to inspire creativity, not squelch it. Higher loads will have an enhanced effect on maximal strength development, whereas lower loads will improve local muscle endurance, lactic acid tolerance, and cardio-respiratory endurance, not to mention fat loss. Not to worry: Some people, due to factors such as fiber-type distribution, hormonal profiles, and training experience, will (at least initially) do fine with straight sets of 5 for the full PR Zone. Others quickly drop from 5's to 3's to singles. The only thing that really matters is the end result, so don't stress if you find yourself "coloring outside the lines." Simply apply the 20/5 Rule in reverse: If you miss your PR by 20 reps or more, reduce your weights by 5 pounds or 5 percent (whichever is more) and re-start. This feeds into the previous question. If you fail to break your PR, and apply the "Reverse 20/5 Rule" as described above, and still fail to hit or break your PR, it's time for a break. What does that break consist of? Anything you like, but for the undecided, I recommend doing a month of the "3-5 Method:" Train 3-5 times per week, performing 3-5 exercises per session, using 3-5 sets of 3-5 reps per exercise, with 3 - 5 minutes of rest between sets. What kind of exercises? Full body acceleration drills: squats, pulls, rows, presses, pull-ups... anything that involves 2 or more joints. Avoid the "terrible triad:" slow, machine-based, single-joint exercises.
