What Does 30X0 Mean? – Why I Like Tempo Training

Slow down . . . it might be your key to avoiding injury and getting stronger.
Tempo training is not just for bodybuilders. Olympic caliber athletes from all over the world use tempo training to become stronger, faster and more powerful. The benefits of tempo training have been touted for years by the likes of Bulgarian Olympians and their coaches to internationally renowned strength coaches Ian King and Charles Poliquin. I was introduced to the benefits of tempo training by my coach and mentor, James Fitzgerald, who uses it very effectively to train many of the top CrossFit competitors.
It’s time for the entire Invictus community to understand how to read tempo prescriptions and understand why tempo training is beneficial.
What Does 30X0 Mean?
Tempo prescriptions come in a series of four numbers representing the times in which it should take to complete four stages of the lift. In a workout, the tempo prescription will follow the assigned number of reps, such as:
Front Squat x 2-3 reps @ 30X0
The First Number – The first number refers to the lowering (eccentric) phase of the lift. Using our front squat example, the 3 will represent the amount of time (in seconds) that it should take you to descend to the bottom of the squat. (The first number always refers to the lowering/eccentric phase, even if the movement begins with the ascending/concentric phase, such as in a pull-up.)
The Second Number – The second number refers to the amount of time spent in the bottom position of the lift – the point in which the lift transitions from lowering to ascending. In our front squat example, the prescribed 0 means that the athlete should reach the bottom position and immediately begin their ascent. If, however, the prescription was 32X0, the athlete would be expected to pause for 2 seconds at the bottom position.
The Third Number – The third number refers to ascending (concentric) phase of the lift – the amount of time it takes you to get to the top of the lift. Yes, I am aware that X is not a number. The X signifies that the athlete should EXPLODE the weight up as quickly as possible. In many cases, this will not be very fast, but it is the intent that counts – try to accelerate the weight as fast as you can. If the third number is a 2, it should take the athlete 2 seconds to get the lift to the top regardless of whether they are capable of moving it faster.
The Fourth Number – The fourth number refers to how long you should pause at the top of the lift. Take, for example, a weighted pull-up prescription of 20X2, the athlete would be expected to hold his or her chin over the bar for two seconds before beginning to come down.
Counting – It seems silly to even mention how to count seconds, but I have heard many clients audibly count to 4 in less than one second while under a heavy load. So, to ensure that your 4 second count and mine are the same, use “one thousands,” as in: 1-one thousand, 2-one thousand, 3-one thousand, 4-one thousand.
Got it? If you need more practice, think about how you would perform the following:
Push-Up x 15 reps @ 2111
Bulgarian Split Squat x 6-8 reps @ 41X1
Pull-Up x 81X2
For many of you, just understanding how to read the prescription will suffice. Others will wonder why they have to follow the tempo prescription.
Why I Like Tempo Training . . . and Think You Should Too.
Tempo training is important at all stages of an athlete’s development – from beginners who simply want to learn to lift weights and shed a few pounds to Olympic caliber athletes of all disciplines. Here are my top 3 reasons for including tempo prescriptions with lifts:
Improved Quality of Movement
Quality of movement should be your first priority. Intensity comes only after one can consistently demonstrate the proper mechanics of a movement. Proper tempo prescriptions can help athletes develop awareness and body control by giving them an opportunity to “feel” which muscle groups are activating to keep them in proper positions.
We work with a lot of kids, and kids tend to be fearless. They think nothing of plunging into the bottom of a squat, secure in their belief that their young, elastic connective tissue will catch and help propel them back to the top. The problem is, as they descend their knees often collapse inward, their chest sinks in and their pelvis rolls into a posterior tilt (the dreaded “butt wink”). By requiring a 53X1 tempo, for example, we can help them learn how to keep their chest up, knees out and lumbar spine neutral by allowing them the time to “feel” those positions throughout the four phases of the lift. If the student is unable to control the descent and perform the movement at the prescribed tempo, we know the load is too great.
In more experienced athletes tempo can be used to emphasize problem areas and shore up weak links in technique. For example, if you struggle in the bottom position of an overhead squat, a prescription forcing you to spend some time in that position will help solidify your technique, create more comfort in that weak position, and permit greater improvements down the line.
Reduced Risk of Injury
Improving the quality of the movement obviously helps to reduce the risk of injury for athletes. But in addition, slowing down the tempo of lifts can ease the stress placed on joints and shift that additional stress to the muscles powering the lift. More stress on the muscles and less on the joints is a good thing. Muscles are far better at adapting to increased loads. Connective tissue typically takes longer to strengthen and adapt to the increasing loads, so by slowing down the tempo you can give your connective tissue some rest while still strengthening the surrounding musculature.
Tempo prescriptions also naturally control intensity (and perhaps, rein in egos). Let’s use the bench press as an example. If you excessively load the barbell you might be tempted to speed up the lowering phase and bounce the barbell off your chest – don’t lie, you do this. But if you know that the prescription calls for a 3 second descent and a 2 second pause at the bottom, you’re not going to be tempted to load anywhere close to the same amount. Don’t believe me? Give it a shot.
Improved Strength Gains
This alone should have been sufficient, but I threw in the first two for all of the coaches out there.
Proper tempo prescriptions can lead to vastly improved strength gains. First, different tempo prescriptions permit for greater training variety and stimulus. This means fewer plateaus and more adaptation.
Second, they allow us to shore up weak links by overloading certain areas of movements. For example, how many of you feel more comfortable with your second and third deadlift reps than your first? I am guessing a lot, and it’s because you are using the benefit of either or both the elastic “bounce” of your stretch-shortening cycle or your rubber plates hitting the hard floor. But if your tempo prescription called for a slow descent and a longer pause at the bottom, you might actually have to get stronger through your weak points.
Third, slowing down movements with tempo prescriptions can allow for greater amount of time under tension with less overall stress on an athlete’s central nervous system. This can be particularly important for CrossFit athletes, who are often pushing themselves to the limits with maximal effort lifts and workouts, by creating a way to continue training and making an athlete stronger without overtaxing his or her system.
Fourth, isometric pauses at the top and/or bottom of lifts force you to recruit more muscle fiber, and more muscle fiber recruitment (particularly more fast-twitch fibers) equals greater strength gains. I know that sounds like coach’s geek-speak, but here’s how you will know you’re recruiting more muscle fiber – it will be really hard.
If you’re not sure yet about the benefits of implementing tempo prescriptions into your program, I would encourage you to try it for a month or two and see if it benefits your lifts. If you’re not sure how to create tempo prescriptions and you are looking for a program more specific to your needs than the Invictus workouts of the day, please shoot me an email and inquire about program design and online coaching packages.
