Intro: The Exercise
The Dimel Deadlift is a great exercise I’ve been using since a while among the many deadlifts variations, I saw this exercise on a video by Dave Tate, I want to him here as he’s always a great source of inspiration and education! The exercise is a variation of the Romanian Deadlifts and it is basically a Hip Hinge based movement that works the whole posterior chain with a very quick inversion from the eccentric to the concentric phase. The idea behind this variation is to make the RDL even more explosive and almost plyometric with very high speeds and short Time Under Tension.
As Dave suggests in the video below, this exercises is good when performed with long sets (15 to 20 reps) and relative light loads (40% of your Deadlift 1RM). Beside making it a great dynamic exercise to be performed during Speed Days to increase power and speed in jumping and sprinting, in my opinion these are good qualities to execute this early in the week during my football season, the day after the game or two days after the game. In fact the longer sets increase the blood flow in my hamstrings and glutes and also the range of movement helps me stretch my muscles. Increased blood flow and Stretch after the game promote a quicker recovery and help me get into conditions for the middle part of the week when I perform my main session in the gym and practices on the football field.
I usually put this exercise on two mini cycles lasting 3 weeks with a waving progression. The first 3 weeks are performed only with plates. I add monster or light bands for the next 3 weeks. The prescription of sets, reps and speed are the same for the two mini cycles. I like to add bands because they accelerate the eccentric phase of the movement allowing me to increase the focus and intensify the inversion of the lift and on the rate of force development.
These are the metrics that I tracked with my Beast Sensor during the exercise last night. I was in the first week of the Cycle.
The Workout Page on the webportal is displaying all the metrics I need to check my exercise and make considerations about future executions of the same.
Sets and Reps : Bars
Every Set has the same colours so you can easily check the 3 big sets of 20 Reps. The bars represent the main metrics and you can switch the display of Power,Speed and Strength. Mean values are represented by the shorter, wider bars and I usually refers to them to check on the development of the metric (I usually rely mainly on Speed). Let me guide to the different metrics so I can show what I’m looking for from the different results.
In this case I’m looking for a constant level of Mean Speed (wide bars) 1) and close to the prescribed target Speed (1.2 m/s for the first week).
It is clear how speed was constant and on target during the same set meaning the load was light enough to allow me to hit the target Speed but not heavy enough to cause a Drop due to fatigue during the set. Since I don’t want to increase my fatigue and add it to the game this is perfect.
It is also clear how speed dropped from one set to the other meaning the 60″ Rest Time was not enough to allow for a complete recovery. This has a good Conditioning effect and helps me increase the blood flow to the muscles. Again, the idea behind this is if I can get blood flowing to the legs without excessively fatiguing them I can stimulate recovery. This is a very delicate aspect of training. I want to stimulate recovery and at the same time I want to have a training effect, mostly as I’m still recovering from the game, I want to avoid overloading myself with a super intense training effect I would need more time to recover from. One strategy to do this is to avoid the In Set Speed Drop which affects the Central Nervous System but to keep a fast paced rhythm so that Set by Set you stay constant or slow down just a little bit. Important to say this next week me and my teammates will be in a bye week so I allowed some extra load by keeping a closed pace. Still I want to mantain the target Speed thou. This fine tuning can be done only with a Speed Tracking device like Beast, there is no other way to monitor this.
As you can see in the Details section below, my Average Speed for the whole exercise is 1.17m/s so I totally respected the prescribed Target Speed.
Power usually has the same development as Speed and in this case as I kept the load constant through out the 3 sets doesn’t say much. It becomes very important when you compare different sets with different weights though. It will be interesting to compare the execution for this week to that of next week. In this specific case I just want to make sure that my average power is close to 1000 Watts, my High Power target zone. I can also check the Average Power for the whole exercise below in the Details Section.
In this case I check the Strength Bars because the exercise has a very unique Strength feature: in the eccentric to concentric inversion of the movement I’m exerting the maximum efforts therefore I check my Peak Strength bars (Thin bars). These are somehow constant, that tells me I’m holding the correct technique of the exercise through the exercise. As you can see the performance is progressively decreasing through the exercise.
Total Repetitions, Volume, Density, Total Time Under Tension
The next section in the Workout Page displays the Exercise Details. The section is designed to quickly check the general metrics for the exercise and monitor the performance actually respects the prescriptions.
In this case Density and Time Under Tension are the two most interesting metrics to me as they give me very interesting insights about my goals. This is also where I get myself ready for some math as the infos I can take out from this data is very useful and describes many different features of the exercise.
A Density 2) of 895 kg/min tells me I had optimal pace for the exercise and needed a little bit more than 4 minutes to complete the exercise. This is quick and intense, just what I’m looking for during a post game session. Also I can collect rep rhythm in many different ways (Density / weight or Total Repetitions / Time) 15 Reps per Minute, very close to game – pace 3) and therefore good for conditioning.
Time Under Tension 4) helps me check the “Plyometric” aspect of the exercise. This is total TUT for the exercise 5). This is close to the correct plyometric time of 0.3″ seconds for “shock training”.
Average Power, Average Speed
These are the two most important metrics detailed here as I can check with a glimpse that Target Speed designed for this session was respected : Average Speed is 1.17 m/s very close to 1.2 m/s.
Also I can check that my Average Power Output for the exercise is a certain percentage of my maximum. In this case I’m around 70% of my maximum average Deadlifting power.
I like to push myself to the limit and monitoring my training performance is a key aspect of my Strength and Conditioning. I like to rotate my exercises frequently and most of all my training parameters change every workout. Being able to avoid overtraining and still keeping an optimal training impulse is like walking on a tight rope and I after my workout I always check that the regulations I did during the lifting session are coherent with my goals and my past performances.
