1. Science Is Self-Correcting – The Case Of The Hip Thrust And Its Effects On Speed

Two new studies just emerged showing that heavy hip thrusts failed to improve sprint speed. Science always leads to better understanding over time. All sports scientists, strength coaches, and those of you who hip thrust for functional performance should definitely read THIS recent blogpost to hear my thoughts on the hip thrust and when and how this exercise should be used.

2. The No Barbell Experiment On Squat And Deadlift And Hip Thrust Strength

A little more than 5 weeks ago I decided to conduct a little experiment on myself. I wanted to see if I could keep my squat, deadlift, and hip thrust strength while sticking to mostly machine training and no barbells. THIS blog post has the full deets of the experiment.

3. The No Barbell Experiment On Squat And Deadlift And Hip Thrust Strength – Results

HERE is the full write-up of the results of my no-barbell-experiment. Contrary to what I predicted, I ended up gaining 20lbs on my squat while losing 40lbs on my deadlift and hip thrust.

4. How to frog pump like a boss!

Here’s a snippet from my latest YouTube video on frog pumps. Please go to YouTube and watch the entire video, as I explain:

-Why people either love or hate frog pumps.
-The two bodyweight frog pump methods that I use: the rep and the squeeze.
-How to frog pump with additional load.
-Alternatives to try if you don’t like frog pumps.

BC’s Top Instagram Posts From the Last Month

You follow me, right? Here are my top posts you might have missed over the last month:

This is great! In the past couple of years, we've seen Sports Illustrated swimsuit cover model @kateupton, NFL linebacker @jhharrison92, actor/former wrestler @therock, actress @gabunion, rapper @50cent, comedian @chelseahandler, supermodel @izabelgoulart, and now former world's strongest man @savickas_bigz busting out hip thrusts. Big Z (Zydrunas Savickas) won the World's Strongest Man title 4 separate times and the Arnold Strongman Classic title 8 times. He has squatted 938lbs, benched 631lbs, deadlifted 880lbs, strongman deadlifted 974lbs w/straps, Hummer tire deadlifted 1155lbs, standing overhead pressed 575lbs x 2 reps, and log lifted 503lbs. He's 42 years old and recently leaned out tremendously. Teachable moment: Many of my followers will be quick to "correct" his form and say he should be looking forward and tucking his chin because that's what I teach lately. You can highly activate the glutes with the looking-up position, but you will also likely activate the erectors to a high degree. If your goal is to strengthen the entire posterior chain or if you've tried both ways and prefer this method, then go ahead and look up. The main point I want to convey here is that Zydrunas has been thrusting for a while and this is the way he likes to do them. You don't correct this; you learn from it. He's activating his glutes just fine. #Repost @savickas_bigz (@get_repost) ・・・ Hip thrust #hipthrust #legday #glutes #hamstrings #gym #gymlife #fitspo #fitfam #strongman #bigz #training #trainingvideos #bodybuilding #bootybuilding #strength #fitness #fit #liftingweights #liftinglife

*Quick Lower Body Training Tip* Don't confuse this tip with leaning forward. You should indeed be leaning forward at the bottom of your squats, lunges, and step ups. The angle of forward lean will depend on exercise variation, relative femur length, ankle mobility, shoe wear, relative quad strength, load, and fatigue. However, whatever torso angle you have at the bottom of the movement, that's the angle that should stick for the first half of the rising phase. Don't shoot your hips up and horizontalize your torso as you rise out of the hole and turn your lifts into good morning hybrids. Make sure the knees and hips extend at similar rates to prevent this from occurring. Keep the back angle solid and your performance will benefit. #gluteguy #glutelab #squats #deadlifts

Please share this so we can clear up this misconception‼️ . I'm sure you've seen the images floating around the Internet showing what 5lbs of fat vs. 5lbs of muscle looks like. The replicas typically shown are a giant blob of fat next to a tiny mound of muscle, and you're inevitably left believing that 5lbs of fat takes up 5x more space than 5lbs of muscle. . This is a myth! 🚫In actuality, the density of mammalian skeletal muscle tissue is 1.06kg/L, while that of adipose tissue is 0.9196kg/L. In other words, fat only takes up 15% more space than muscle. . So 5lbs of fat weighs the same as 5lbs of muscle – obviously! But muscle is only slighter more dense than fat. . How did this misconception arise? I do not know, but I surmise that some sleazy marketer fabricated the idea to sell a product or service by dramatizing the visual effects of getting into shape. 🤷🏽‍♂️Whatever the case, this individual clearly never chased down the science like I did. Unfortunately, these images are so common nowadays that they aren't questioned and are passed along as fact. Exaggeration is never a good idea; people deserve the truth. 🙌🏽 #science #fatloss #muscle #musclescience #fitness #bodybuilding #gluteguy . References: . 1️⃣Lohman TG.

In other words, most people should CTFO and CTFD (chill the F out & calm the F down). #gluteguy

    For what it’s worth, these are my favorite posts. Reading articles and listening to podcasts, even if the information is old news to me, is still motivational to me to get my ass working out on those hard days. This saves me the trouble of searching for new sites as old ones stop updating.

  • mabel harri says:

    One question that has never been addressed or answered: Should hip thrust be done before or after squats, before or after deadlifts?
