Fiddleman 4,376 Posted June 6, 2014 Sprinting is known to really increase the T for leaner, stronger and more fit bodies, so I thought, why not. Strapped on my hr sensor and put on my polar watch. Resting hr: 55 5 minute dynamic stretch (up to 95) 5 min warmup @ 6.0 mph (up to 125) For 10 minutes (got treadmill up to speed before starting) Jump on Sprint 30 @ 12.5 mph and 3 incline (up to 161) Jump off Rest for 30 s -- (down to 155) 5 min cool down jog (down to 99) Static stretch ( down to 75) As you can see, I just barely went anaerobic (160 is bottom of my anaerobic zone) during the sprinting which means I need to increase the incline a tad. Speed is already booking. By sprint 8, quads were feeling the burn. But hey, we can do anything for 30 seconds. The interesting part is my hr did not drop below 155 even when resting for 30 s. Man oh man. It went by so fast (5 minutes) , yet gave me a REALLY good fast and furious cardio day. And because sprinting really requires you to be focused (especially on a treadmill), no boredom. It is over before you know it. There are many articles correlating sprinting with higher levels of T. Kind of like cross fit where workouts usually max out at 20 minutes, but are oh-so-intense, pushing you into that magical anaerobic zone. Don't just take my word for it. Here are a couple articles: http://www.livestrong.com/article/353949-sprinting-testosterone/ http://www.lifehack.org/articles/lifestyle/8-hacks-to-naturally-increase-your-testosterone-levels.html And my personal favorite by mike Mathews (great guy and great resource for thinking outside the box on body building and fitness in general): http://www.muscleforlife.com/how-to-increase-testosterone/ Less work for greater benefits? That's an A in my book. Try it out. 2 naenaern777 and swimbikerun reacted to this Share this post Link to post Share on other sites
swimbikerun 1,046 Posted June 6, 2014 Someone suggest a love this button. Great job as always Fiddleman!! Btw ... just so you know ... for most women, whether or not you have T in the body is not as important as $$$ in the bank. LOL I couldn't resist! 1 Fiddleman reacted to this Share this post Link to post Share on other sites
