NEW EQUIPMENT INCOMING 👀🔥
We’re adding some new toys to MRT!
New REP Stone Sandbags 2.0 are on the way — giving us even more options for carries, strength work and some absolutely terrible ideas our coaches will come up with. 😂

📅 Saturday, October 10
⏰ 10:00 AM–2:00 PM
We’re continuing to build out the equipment and setup to give athletes the best ATHX experience possible and replicate the competition flow as closely as we can.
More equipment. More ways to train. More coming. 🔥
And if you haven’t registered for the ATHX Simulation yet — spots are open!
Why working out is more than just for your body!
Brain Chemicals and HormonesEndorphins:
✅Physical activity releases endorphins, which are natural brain chemicals that act as mood elevators and pain relievers.
Serotonin and Dopamine:
✅Movement stimulates neurotransmitters that regulate emotional stability, happiness, and motivation.
Lower Stress Hormones:
✅Workouts reduce levels of cortisol and adrenaline, the body’s primary stress hormones.
Brain Structure and FunctionBDNF Release:
✅Exercise triggers Brain-Derived Neurotrophic Factor (BDNF), a protein that helps grow new brain cells and strengthens neural connections.
Improved Blood Flow:
✅Increased circulation delivers essential oxygen and nutrients to the brain, enhancing focus, memory, and cognitive sharpness.
Psychological and Behavioral BenefitsMental Distraction:
✅Working out breaks the cycle of negative thoughts by giving your brain a positive focus.Better Sleep: Regular activity helps regulate sleep patterns, leading to deeper rest and better daytime energy.
Higher Self-Esteem:
✅Meeting small fitness goals fosters a sense of achievement, strength, and personal control.
