Kinja'd!!!

I think of my fitness as a car. Right now I view my peak torque to be my 1-rep max for the exercise. My horsepower would be what I do for 3-sets of 6-reps. I havent sat down and figured out the cardio to fuel economy conversion but I know I “measure” over a 15 minute test cycle.

Neat. S, what are the figures?

In theory you could convert bar acceleration/speed with a given weight to Watts and Horsepower. “Economy” should be how long you could perform a certain task above a set threshold, aka a rower above 30 spm or a bike at however many watts. There was an old challenge on I think T-Nation that was 1 deadlift at 315 or 2 reps EMOM for a half hour.

ugh, converting human power to HP is always depressing to me. I can keep up like a quarter HP for almost an hour... Better off leaving it in watts, it sounds better.

I just made this up this morning so I havent done a workout focused on testing towards it. I wanted to see if others had different ideas, suggestions, or do something like this.

That doesnt seem as fun or as quick as picking something up. I need something that will keep me entertained while Im exercising because my mind drifts away.

Now you’ve got me thinking. Is the deadlift the best choice (of the big 3) for this because it uses the most muscles and has the highest potential, or is it something like a bench press where bar speed can be faster?

PS that challenge is brutal.

Power = Work / time

Work= Force x Distance

Force =Mass x Acceleration

If you can deadlift 185kg (405#) to 0.5 meters (about your knees) 5 times against earths gravity in 10 seconds then it looks like...

F = (185kg)(9.81m/s/s) = 1814.85 meters per second per second or newtons

W = (1814.85N) (2.5m) = 4537.125 newton meters or joules

P = (4537.125J) / (10s) = 453.7125 joules per second or watts

1 watt = 0.00134 horse power

453.7125watt x 0.00134 hp/watt = .608hp

Pick up heavier weights, your mind won’t have the option to drift.

If your technique is tight you can deadlift pretty fast, the issue is the reset when it hits the floor. That challenge is way tougher with a true deadlift, we attempted it trap bar and stretched it to an hour and it wasn’t bad.

The other one from an old fitness mag in a Rob Orlando column was pick a lift and do 10,000lbs of volume as fast as you can. That one really sucks.

Touch and go is cheating the challenge, IMO. Stretch reflex.

There were a lot of Roberts in the Matrix, though.

Or compete in Strongman and just deadlift cars.

Opinion: vast majority of people don’t have solid enough technique or good enough control of the weight to TNG anyways. The 2nd rep almost never starts from the same position and follows the same bar path as the first.

Not sure I follow, Rut.

Most people I see TNG all day and then wonder why they are poor off of the floor. You’re right regarding the 2nd rep, but they’re typically easier since you aren’t actually pulling dead.

The 2nd rep is typically easier, but if it bounces most people will lose tightness and they tend to not keep the bar nearly as tight to the body. Once the bar is out hips come up, psoas can end up strained and the lift gets way more likely to miss.

I’m on the flip side where I am strong off the floor and missing lockouts.

In a scientific sense, the work done by weight lifting is almost zero. It takes almost the same force in lifting and lowering the weights and everything returns to its original position.

The thermodynamic efficiency of exercise feels even worse. Go ahead and calculate the WORK done during exercise. Next, compare that to caloric intake. Keep in mind that most of the energy put in your body that is not expended as work will be heat.

The efficiency numbers are tiny.
