Also like to add, I usually am an advocate for running outside on real ground but, we're having a serious haze issue right now cause of Indonesia burning their palm crops and it's causing allot of respiratory issues with the public so, for now I just balance hitting the muscle groups missed by putting the mill at 25-45 degree incline depending on what I'm doing... ✌️

Google is okay if you wanna look up research studies but,... If you're following the right people on YouTube; most of them provide links to the research studies that they site so. Maybe it's cause I'm older but, when we wanted to know something, we had to go to the library and research what research there was, ( I know, I sound like the proverbial "grandpa", with the whole, " back in our day...",), but, in general, folks today don't do this, they just copy what they see that looks appealing, and even some ,"fitness", studies can be misleading nowadays, ESPECIALLY when it comes to the supplement industry. But anyways,...

@Hampton Lansdowne thanks bro

Well, I haven't went through any of the training programs "perse", but, I've been using allot of the training exercises, practices, movements, etc... from your content on YouTube for the last couple of years now and it's helped tremendously, especially some of the reflex and rebound training involving my ankle, knee, and hip as I had pretty significant nerve damage due to an auto accident, ( got hit by a truck walking home one night in January 2012, Sub-Zero, ice, sleet, ..long story short I had to learn how to walk again and build back from there.) but anyway, I plugged in allot of your MMA/ combat content as I've been practicing boxing n martial arts since I was about 6. That and allot of your corrective exercises/ movements helped significantly. As of now, I'm jogging 10-15 miles a week, ( just managed 2.97 miles in 20 minutes the other day),.. I'm hitting almost 800lbs. On the reverse pendulum squat machine, ( I can't mechanical load too much on the barbell squat cause of some nerve damage in my neck and between my shoulder blades),... My overall strength and power endurance have elevated significantly as well.. Honestly I could keep going in detail but,.. plain n simple,... ALL of your training info, data, input, content, practices, that I've implemented have helped more than I can really express. You're a blessing to all of us who have found success in our training, be it physical, mental, spiritual. May you and yours be blessed in all aspects of your life and many more blessings for your future brother, InsyaAllah Aameen x3 🤲 👍. Assalamualaikum brother. Lead the way..
