Essential Random Gym Thoughts Revisited...

[unit321]

Dont sleep on leg press brehs. Im gonna say it. IM GONNA SAY IT GOD DAMN IT. Leg press >>>>>>>>>>>>>>>>>>>> front squats, for pure quad development. I might even go as far as to say leg press >>>>>>>>>>>>>>>>>>>>> * for pure quad development. Hear me out

My last heavy back squat day, I hit 5x315 on my last set of 3, with a paused last rep, which was a PR. A couple days before, I jumped on leg press for the hell of it, for the first time in years. I got up to 10x400. The sled is 80lbs. So that's ~480lbs. You take out the angular component (~30%, I am assuming it had a 45 degree angle), that's still 340lbs at my feet. For 10 pretty easy reps. On front squat I was happy to get ~165 for 8 and I was shaky as fukk the whole time. I enjoy squatting and will keep doing the back squat.... but if you want to turn up on quads, def give leg press a try. I was really surprised with how much weight I could move and how easy it was. Squats are good but you are limited by core strength and silly shyt like not wanting to get crushed by hundreds of lbs of weight.... leg press takes all that shyt out of the picture and just blasts your quads

Uh huh. This is going to be your downfall.
Get away from leg press as a primary exercise for quads if that's what you're thinking.. Use it as a secondary exercise or not even at all.
Work equals force x distance. the leg press is giving your body less work to do, there's a reason why it was easier than the front squat. If your knees are shaking at 165 lbs, that means you need to work at it, not switch to a machine that makes you "feel" like you are stronger.

I feel what you're saying, I'm just not trying to put like 5-6 plates on each side

I ain't got time for that

Yea that shyt is no fun. They have 100lb plates at my gym though

Leg press isn't my primary quad exercise, back squats are.

And work = force x distance. The distance is shorter, but force = mass x acceleration. Mass is way bigger, acceleration is a little stronger, and I'm doing more reps. Your quads don't care if you front squat, back squat, leg press, stairmaster w/e... they just respond to a workload. If you can load them up more with an easier movement why not incorporate that as well? There is no proof that quads respond better to squats than leg press.... plenty of athletes use leg press exclusively and have huge quads (sprint cyclists).

That's true.
The distance is shorter. Less distance = less work. You could do the same thing with squats. Load up with your one-rep max but add 90 lbs. Go down not even 1/4 of the way and come back up. The 1/4 squat is an easier movement, right? You can even accelerate faster since you're only dropping a foot or less.
And to push that analogy even further, load up with 180 lbs on top of your one rep max. Lift it off the squat rack pegs and lower it two inches. Call that one rep. Again. mass is way bigger. Acceleration is stronger, and you could do more reps. And before you call preposterous, I've seen people do that.

I see it like this. I'm looking at it from the quad's point of view. When I squat my knees probably go to like a 100 degree angle. When I do leg press I take my knees to about the same degree of flexion. I did the trigenometry. With 400 on the leg press my feet are seeing ~340lbs of load. The distance my quads are pushing the weight from my quads point of view is the same. So naw, its not cheating or w/e you are trying to suggest. If you can find some scientific proof that front squats >>>>>>>>> leg press for quad growth I'll toss leg press, but I haven't seen anything to that effect. If anything I've seen the opposite

So just to make things clear, if leg press works for you. That's fine.
I bolded the sentence you said. You see, a leg press machine has an angled sled. The leg press is a "simple machine'. You put a weight on an inclined plane, and you can lift more than you could if you need to lift it vertically. You really don't know how much weight you are pushing at the feet, you can't use trigonometry to calculate that, that's physics. And, you aren't involving stabilizer muscles, that you use in a squat, so you can leg press more than you can squat. If you aren't doing other sports, then it's not big deal. If you are using weight lifting to build muscles for another sport, then there's an argument to be made against the leg press.

You can use trigonometry to calculate it. Trig is a huge tool in physics. Full disclosure, I am a licensed engineer. The leg press is a classic incline kinematics problem. Here's what's going on in a nutshell:

The angle is 45 degrees so sin/cos are both ~.7 (1/sqrt(2)). F = the weight of everything my feet are pushing on which is the sled (80lbs) and the weight on it (400lbs). Fsin0 is the force my legs are counteracting. 480 * .7 = 339.4lbs. I'm not an athlete... I do cycling and I swim a little bit but my main goal is general conditioning and aesthetics. Even if I was though, leg press is still a good tool. Like I said, I know pro athletes in various sports who use it, especially in cycling. Like I also said before, don't knock it till you try it. There's no heroism or honor in picking one exercise over another if they both help you reach your goals

Back on my 5 by 5 workout regime felt so goood

You dudes getting hella technical over this shyt. ct fletcher frowns upon your shenanigans

I fukking hate colds

I wanna lift

 

[semtex]

I ain't ever taking zinc again after last night. Wicked stomach ache that would not go away

Yea I had to dead zinc and even vitamins. shyts do numbers on my stomach, empty stomach or full.

This will sound strange but maybe 2-3 runs ago, I started listening to music while running and it's made the whole experience pretty enjoyable. I haven't looked at the scale in 2 weeks and my goal is not to even touch it until the end of the year. I will say I feel a lot "lighter" when I'm running and for the most part I can manage a steady pace throughout the entire run. The hills are still tough but I'm just lucky to have decent enough weather to still get out doors.

I'm surprised you just started. When I was running distance that's what helped me keep pace and push through. Oddly enough I'm moving away from head phones during lifting. It's a distraction now.
