## Overview

SPORTLEGS Fast Fitness Boost is a patented, stimulant-free pre-workout supplement designed to optimize muscle endurance by enhancing the body’s natural lactate fuel system. NSF Certified for Sport and trusted by elite athletes, it reduces lactic acid buildup to minimize muscle burn and soreness, enabling smoother, longer training sessions from the very first dose. Vegan, clean, and made in the USA, SPORTLEGS is the go-to endurance fuel for runners, cyclists, and fitness pros seeking a competitive edge without compromise.

## Description

Patented SportLegs pre-workout supplement works to prevent lactic acid muscle pain. You get to perform your best, like you trained an extra month. Or turned the calendar back a decade. HOW SPORTLEGS IS DIFFERENT: SportLegs isn’t another hot weather sodium electrolyte. Instead, it duplicates your body’s natural signal to curb excess muscle fuel production in time to prevent lactic acid. SportLegs raises blood lactate concentration exactly like strenuous exercise does. But it sends that signal early, before exercise, to prevent the excess lactate muscle fuel that degrades into lactic acid, the primary source of muscle “burn,” cramping and next-day soreness. “SportLegs really works,” agree USA Today, Bicycling magazine and SKI magazine. “My University Sports Physiology professors say the idea behind SportLegs is ingenious,” writes one triathlete. “We can’t understand why somebody didn’t try this sooner.”. Using your body’s natural chemistry, SportLegs is safe, healthy and legal. It has become #1 in US cycling. It works so well, there’s no reason not to use it.

Review: Definitely works and a high quality product
Review: These really work when your legs or body is taxed from working out constantly. Definitely give you more endurance and easy pills to swallow. GAME CHANGER for doing multiple shows or running a marathon or working out a long time with intensity.

## Features

- A DIFFERENT KIND OF PRE-WORKOUT. Not a stimulant and not an electrolyte drink. SportLegs prepares working muscles before hard efforts so movement feels smoother and more sustainable from the start.
- SUPPORTS THE BODY’S NATURAL LACTATE FUEL SYSTEM. At the beginning of exercise, muscles typically produce lactate earlier than they can efficiently use it. SportLegs helps muscles use that fuel sooner, reducing the “heavy legs” feeling that normally fades only after weeks of training.
- HOW WORKOUTS FEEL DIFFERENT. Users commonly report steadier pacing, less burn, and a smoother rhythm during runs, rides and long training sessions - the feeling athletes normally reach only after they are fully in shape.
- TRUSTED WHEN IT MATTERS. NSF Certified for Sport and used for decades by runners, cyclists and endurance athletes from local races to Olympic competition. No stimulants, no sodium, no harsh buffering ingredients.
- SIMPLE PRE-ACTIVITY ROUTINE. No “loading” period. Works on Day 1. Take 1 capsule per 50 lbs body weight 30 minutes before activity. Vegan formula with lactate, calcium, magnesium and Vitamin D. Made in the USA with premium global ingredients. No caffeine, sugar, sodium bicarbonate, dairy, gluten or GMOs.

## Questions & Answers

**Q: Does it help with running or just cycling?**
A: I would say that it helps more for cycling, just because cyclists usually work out for longer periods of time. I am a 60 year old mountain biker and if I riding or racing for more than 2 hours, Sportslegs or something to prevent cramps is a must. I get leg cramps and cramps in my hands especially when it is hot and I am sweating. You will be surprised how quickly they work. I keep a baggy with about 10 capsules tucked under my bike shorts. When things go south you can take one every 20 minutes or so.

**Q: Will i lose my gold medal in rio if i take this?**
A: Hello!  Our guess is that if you're participating in the Rio Olympics you've already got a nutritionist telling you what to eat...but for the rest of us these are a good supplement to take.  Thanks!

**Q: What are the active ingredients beside sodium and calcium? Is this the same as an electrolyte pill?**
A: There's no sodium in SportLegs. It's not an electrolyte. SportLegs is 88% premium European natural-source lactate. Taken before exercise, SportLegs raises blood lactate, replicating the natural signal muscles obey later in exercise to curb excess lactate fuel production. Modern imaging research shows excess lactate production is the source of lactic acid. SportLegs is a clever, healthy way to help prevent lactic acid in the first place. Balanced calcium, magnesium and vitamin D are included to speed absorption.

**Q: Why is the single bottle of 120 tablets 3.84 oz and the 3 pack of 120 tables each is only 9.6 oz?  It should be 11.52 oz for 3 bottles.**
A: Poor proofreading.
