I've been seeing a lot of chatter about lengthened partials lately, like how they supposedly help with hypertrophy and building that crazy muscle endurance. But where's the real research at? Anyone got studies or solid data on this? I'm curious if it's just gym bro science or if there's something to it. Let's get into it!

  Honestly, I think it's a good idea to give lengthened partials a shot. I started doing them for my deadlifts, and I feel like they've helped with my endurance. Just don't overdo it, nobody wants to walk around like a pretzel! 😂 Keep the focus on quality reps.

  Lengthened partials are pretty interesting, especially when it comes to hypertrophy. There's some research suggesting they can maximize tension in a muscle by keeping it under load throughout a greater range of motion, which could lead to increased muscle growth over time. Some studies have looked at how this method might also enhance metabolic stress, which is a key factor for muscle adaptation. If you want to dig deeper, I'd suggest checking out the work by Mike Israetel, who often discusses the importance of varied training strategies for hypertrophy

  I think lengthened partials can be great for some lifters, especially those looking to increase their time under tension. It's kind of like yoga; you hold certain poses longer to really engage those muscles. Plus, I've found they can help with my overall lifting form by reinforcing strength at the bottom of my lifts. Just remember to balance them with full-range exercises for well-rounded development.

  There's definitely a place for lengthened partials in training, particularly for targeting weak points in lifts. If you're using a safety squat bar or a slingshot, you might find that incorporating these can help you break through plateaus. I've used them in conjunction with my regular lifts and seen solid improvements in my squat depth and overall stability. Just keep in mind that technique should always be your priority. Overloading without control can lead to injuries.

    This whole lengthened partials debate is kind of ridiculous. It's like saying all I need to do is lift weights halfway and I'll magically get swole. I mean, sure, there's some science behind it, but do I really want to go half-ass on my squats? Give me a full range of motion or nothing! Also, cardio is hell, but at least it's not pretending to be something it's not. Gym bros, man.

    Facts! I've heard a lot about these but never tried them. I'm all for mixing things up in the gym, tho! 😄 Sometimes, you gotta get weird to find what works.

  Ngl, I'm skeptical about lengthened partials. It sounds cool, but I'd rather focus on solid nutrition and recovery. Building muscle is a combination of training, eating right, and resting. If you're not hitting those macros, no amount of partials will save you!
