Sport Legs Product Review

Sometimes you come across a product that you love so much that you want everyone to be able to reap its benefits. SportLegs is an amazing product that I have been using about a month now but I never want to do another leg work out or long run without it.

I’m sure we have all been excited to go out running but soon after we begin we realize that our legs just don’t want to cooperate, they feel like they weigh 100 lbs. There is no better way to ruin a perfectly good run than to deal with tired legs.

... A month ago I found SportLegs, I decided to take them on my “leg day” I got done with all of the squats, lunges and a whole array of hard stuff. I then headed into a spin class. I found myself going crazy, I couldn’t feel any pain or discomfort in my legs, usually it is quite difficult to do a spin class or run for that matter after working my legs. I was flying and it felt awesome. After the 45 minutes of spin I headed out for a quick little run. I did a 5K faster than ever before. I then went home and took another pill to help lessen any soreness that I could have inflicted upon myself. The next day I was sore but it was not near as bad as I thought it was going to be.

The next Saturday was my first 18 miler of the year that was NOT to be completed on the treadmill. I woke up and took SportLegs. Two weeks previous to this one I had gone on a 17 mile run outside and by mile 14 I just wanted to blink myself home…I was DONE. This time though was a very different story. I felt AMAZING! I think I could have run all day long, my legs weren’t tired at all. I didn’t have anything holding me back. In fact, once I got home and drank my protein shake I went on a 4 mile walk with my kids.

The good thing about SportLegs is that you don’t have to take it every day there is no “loading” where you have to take it for a few weeks in order to start noticing its benefits. You take it 1 hour before you start exercising and again after your work out is complete, if you want to help ward off excessive soreness.

Here is what Sportlegs.com has to say about the science behind their amazing product:

Lactate, commonly called lactic acid, is turning out to be seriously amazing stuff. Science no longer regards it as a waste product of anaerobic exercise, as was thought for most of the 20th century. Lactate is now recognized as a key carbohydrate muscle fuel source which muscles produce, exchange and consume both at rest and during exercise. And it's the primary ingredient in SportLegs. What's alternately termed the Lactate System or Lactic Acid System is now recognized as the primary source of energy for short-term "sprint" activities. Since most competitive sports are nothing more than sequences of sprint activities, lactate remains a focus of current research. For instance, during exercise, it's recently come to light that your blood may actually transport more lactate than glucose to fuel muscles (20). At rest and during light exercise, your muscles balance lactate production and consumption, producing just as much lactate as they consume (21). But kicking up the pace upsets the balance:

When you start serious exercise, muscles produce more lactate than they consume (1,2,3,4,5), particularly at altitude (2,6), which is why skiers and mountain bike racers suffer more "burn" than most. This continues until the concentration of lactate in your blood rises enough to signal muscles to stop producing excess lactate (7,8,9,10,11,12,13). Until this happens, a domino effect begins which limits your subsequent performance: Lactate accumulates in muscles; limbs "pump up" and feel heavier. The harder you exercise, the more lactate accumulates (14). Lactate accumulated from flow imbalance quickly becomes acidic (14,15) and even less mobile (16), further exacerbating accumulation. This "Lactic Acidosis" is classically associated with reduced Lactate Threshold, reaching the "burn point" at a lower level of exertion. Muscular strength plummets as well (17,18,19).

How taking SportLegs first helps performance: SportLegs uses lactate, your body's primary high-exertion muscle fuel, to signal muscles not to overproduce lactate before you even begin exercise. Muscles switch from lactate overproduction to net lactate consumption in response to a rise in blood lactate concentration, regardless of whether blood lactate is raised naturally or from exogenous infusion (7,8,9,10,11,12,13). That's precisely what SportLegs accomplishes. It's 86.4% lactate. Taken an hour before exercise, SportLegs raises blood lactate, so you experience exercise with less limb "pump" and heaviness, and improved lactate transfer facilitates a noticeably higher Lactate Threshold. Reduced lactate accumulation means less retention of free radicals and other metabolic wastes in muscle tissues, for faster recovery and less next-day soreness.

SportLegs also contains calcium and magnesium, which are two things that are lost when we sweat. You don’t get calcium or magnesium from sport drinks. SportLegs is one supplement that I would recommend to anyone who loves to run but hates that heavy leg feeling that drags you down.
