can be annoying when beginning a training program. It’s usually weakness, and how it can be easily addressed is by slowing the tempo to introduce loading through the joint. This can allow for a more favorable entry point prior to training heavier. Don’t sleep on tempo especially for when you have aches and pains.

Do you leverage tempo in your training?

How precise does BFR really need to be? And does more precision always mean better results?

New episode of the BFR Better for Results Podcast is live. I sat down with Dr. Warren Bradley, PhD, co-founder of Hytro, to debate the trade-off between the “ideal” protocol and the one athletes will actually use consistently.

We get into:

How much pressure precision actually matters
What the evidence says about BFR for recovery
Intermittent BFR and neuromuscular recovery
BFR during aerobic work
Safety screening and why tolerance matters
Reperfusion and vascular response after cuff release
Practical BFR vs clinical cuffs
How pro teams use BFR for recovery, warm-ups, and travel
Hytro’s funded PhD research program and where the field is headed
Lab meets real world. Some agreement, some pushback, all useful.

It really be like that sometimes. The most random people critiquing or offering with absolutely zero credentials or expertise.

Imagine some random coach critiquing for his posing. 😂

One of my go to beginning to advanced exercises - meaning it is appropriate for everyone all the time because of the stability it has as well as the overall ability to enhance its ex*****on via manual cueing. For those with sensitivities in sitting from or , maybe we’d want to keep the spine in more extended positions. That’s fine, let’s load it. For those that need more tactile cueing to encourage proper form, book it! All in all, the fine-tuned ability of this machine to address everything we’d need in a program targeting the lower .

Remember: rule 1 of is don’t get injured. Number 2 rule is optimize your movement patterns before trying to load them. Easier to hit the targeted muscles for better longevity and reduced compensations.

For this pattern, I showed my client’s difficulty in adducting the shoulder without excessively recruiting the middle scapular muscles. This is both a coordination issue as well as a load based issue. The machine allows us to add as much support as needed to normalize the pull. Then we load.

As fall begins, I’m still a and physical therapist, and most of all, continuing to manage my intermittent . Today was a ton of standing, moving, and carrying my daughter, because I saw patients/clients, grocery shopped, and played Dad of the Year by entertaining my daughter for a couple of hours while my wife prepared for an important presentation. At the end of the day, while I may have felt physically exhausted chasing around a rambunctious toddler, my feet felt brand new!

Wearing the neutralizers, which maintains some of the type gains I’ve achieved with the strengtheners I’ve worn in a prior video, it helps keep my feet in the best alignment for my own foot type, something that is unique to the Good Feet Store because each person goes through a personalized examination to know which of their arch supports best fits them. Their 3-step arch support system is a comprehensive approach to restoring better foot posture so that when I am on the move all day (which is most days, btw), I can know that I’m having the support I need from the moment my foot hits the floor...x 10000 steps or so.

If you are questioning whether they may help you, they have a 90-day customer satisfaction policy where they will work with you to make it right if for some reason you’re not happy...and if it doesn’t turn out good enough, they won’t charge you a restocking fee to get the refund. It’s that simple. Not to mention, the people I’ve interacted with on all levels of the company are class. Highly recommend and support them. If you got something going on in your body (which most of us do, statistically speaking), check them out!
