@drethankellum: Which one did I get wrong? Tell me below. How do you know if a fitness trend is worth your time? Ask one question before you start: could I still be doing this in five years? Most trends are built to go viral, not to last. They promise fast results, they're extreme on purpose, and they usually leave out recovery. That's why the injury tends to show up a few weeks in, right when the excitement wears off and the fatigue piles up. A few things that separate a good program from a trend: It gets harder gradually. Progress should come from adding a little over time, not from punishing yourself on day one. It has rest built in. Your body adapts between sessions, not during them. It includes some form of strength training. It doesn't hurt your joints. Muscle soreness is normal. Sharp pain or joint pain isn't the price of results. And the boring stuff counts. Sleep, protein and walking never trend, but they carry most of the results. I ranked the biggest fitness trends from S tier to D tier in the video, and a few of the most popular ones land right at the bottom. #fitnesstrends #tierlist #75hard #strengthtraining #orthopedicsurgeon

Walking is S or A tier so it is low and rucking is rough on knees real rough it’s c tier.

75 hard isn’t just about working out, its about changing habits,changing how live, not just working out.

wrong about ice baths, 75 hard gives you 1 rest day a week, Rucking isn't good for your joints, you CAN spot reduce but its not like what people think.

Lifting doesn’t need to be heavy, I think progressive overload is the better approach

75 hard doesn’t make sense until you do it. I’ve never seen so many people get in shape from it even though it’s not perfect. And the seven day a week thing could be an easy walking rest, stretching, or light mobility as well.

Dr. Bruce Guillory, D.C. :
75 Hard has been fantastic for me. I start every year off on January 1 doing 75 Hard. You don’t have to work out hard every single day. Many times my workouts are just two walks that day. It knocked 15 pounds off of me the first time I did it. It cleared up a lot of inflammation in my body because I ate totally clean for 75 days and had zero alcohol. I’ll be doing it again in January 1, 2027. Join me!

I think you need to look closer at CrossFit programming. It’s isn’t just heavy lifts while exhausted.

I put aerobic exercise as important as weights. I do both and the cardio fitness is fantastic to have

Agreed! That’s why I love Lagree, it’s like Pilates, but with added weights. That combined with heavy lifting at the gym has helped me reach my goals.

Yoga teacher here, hot yoga is fine but if you can’t breathe properly it destroys the purpose of yoga
