Most of us have finished our autumn marathon season and we are on the way to the Christmas season of recovery! My big races are complete, but I’m not in full relaxation mode, since Hyrox returns to Chicago, and that is where I will be this weekend.
I have been tilting to the extreme resistance in this marathon season for recovery assistance and I am increasing my dose this week while my body works to recover from a challenging race of 10K on Saturday and the brutal hills of the Madison marathon last Sunday.
First I discovered the extreme resistance in IG and immediately intrigued me, partular of its recovery aspects.

This product is made by a company called Xendurance, a company based in the United States, and covered this product a little more in my October history here.
I am ready to compete on Saturday at 5 PM and focus on recovery and hydration this week to prepare for this exhausting physical conditioning competition. I have competed in Hyrox three times before and this will be my first extreme incorporation in my training cycle.
The race has 8 functional aptitude movements with a 1 km race between each exercise. Athletes are divided into groups depending on gender and age and start a starting ramp with a Hyrox team member that not only checks the rules, but pumps it.
The athletes begin with a 1 km race, which in Chicago translates into more than 2 laps around the outside of the exercise station. After the race, the athletes make the transition to the skierg, where they have to complete 1,000 meters from the upper body and the back action.
After the skierg, the athletes will once again hit that 1 km race on the outside and will enter the number two, which is the most challenging. As a strength challenge corridor at the top of the body, pushing a sled is a great work effort. The training requires four laps or 12.5 meters that push a manio that weighs 226 pounds for women and 336 pounds for men.
After Sleed’s thrust, there are six more events, each interspersed with a race.
4 x 12.5 m of management – 225 lbs / 225 lbs (each of the inclined)
1 km run*
80 m Burpee Broad Jump
1 km run*
1,000 m rows
1 km run*
Roy 200 m kettle Bell Carry – 2 × 35 Ibs / 2x 53 Ibs
1 km run*
Lunge of sand bags of 100 m – 22 pounds / 45 pounds
1 km run*
100 x – 10 pounds / 14 pound wall balls
This competition is extremely hard for the body, and my body is certainly not in the maximum training way after my autumn marathon season, so I am a little nervous about how this works. However, Extreme Endurance is designed to help in rapid recovery times and to increase sports performance, so I am leaning on that. The real product also goes beyond athletic use. In a recent study, Dr. Robin Mcnelis. A physiotherapist, health coach and independent athletics coach who worked in London, Scotland, discovered that the product helped in a long covid recovery.
The physiotherapist Robin Mcnelis was a marathon corridor of less than 3 hours, with 19 marathons completed over the years, when unfortunately he contracted Covid-19 in March 2020 results in a blood clot in his lung and pericarditis (inflammatory around his tip). After having both treated successfully, Robin developed the presentation of chronic fatigue of the Syndrome after Covid/Covid Long. Dr. Mcnelis pleaded using extreme resistance at the beginning of 2024, not to boost (we know that does not work with Covid Long), but to minimize any relapse of symptoms if accidentally exaggerates things. Hello, Immune Boost also used to try to reduce the impact of any lower infection that had bone that also hinders progress.

I will report after this weekend to let him know that Hyrox left and if I felt any difference in performance with extreme resistance.
