  1. great product

    Posted by Mike B on 22nd May 2015

    Very impressed with wilderness athlete. The 28 day challenge got my life on track and have never felt better. I will continue to use these great products.

  2. Great Start

    Posted by Marcel Kozyn on 22nd May 2015

    First off, the customer service is excellent. I had to make a call to find out where the guide and tracker was. I got Kevin on the line and he immediately sorted me out. He asked for email updates and he replied to them. It's always nice knowing that the company cares enough to hear how you are doing.

    I am 46 years old, retired Canadian army vet with a buggered up back from an injury in my early twenties. I am an avid hunter, fisherman and I love to be outdoors. Since retiring from the military my physical condition and health have back slid drastically and I was getting ashamed to look at myself in the mirror. I went spring bear hunting this year with my son near my home on Vancouver Island. The hiking up and down the mountains while carrying my pack killed me. I knew I had to change something and fast. I was looking for a kick start and I found it,

    I have never used a weight training supplement so I was a little apprehensive to try this. I have the good fortune of being friends with a former Mr. Universe competitor so I asked if he would look the products over for me. He did and he was very impressed and gave me the thumbs up.

    All the products except for the Green Infusion have great flavor. I would start off with the superman drink and lean body pills then a 45 minute cardio and stretch workout. I would then have the meal replacement shake with the green infusion and the multi vitamins for breakfast. I would not be hungry until close to lunch time so it keep me going about 5-6 hours. In the evening I would do 45 minutes of strength training and weight with the hydrate and recover. I made diet changes as well, no more deep fried, take out, or my beloved desserts.

    Using the 28 day challenge and enlisting the help of a friend I was able to change my lifestyle. In the 28 days I lost 10 lbs total, lost 2.5 inches off of my waste and 1.5 inches off of my thighs. I did achieve my goal of dropping a pant size and shrinking my waste. I feel great! My back feels better and I have way more energy. It is really nice to be back in a workout routine that has realistic goals.

    I have ordered some more stuff as I have a few more inches to loose and a lot more strength to gain. Somewhere on a mountain in Northern British Columbia there is a Big Horn Sheep that is just dying to come to my place to dinner, and I hate to leave him waiting!

    Buy with confidence, use as directed, and become accountable to someone to achieve your goal.

    Good luck!

  3. Great flavors

    I've tried all the products, love the flavors and that there isn't a lot of sugar in them since I'm diabetic.

  4. Helping me stay on track

    Posted by John on 14th May 2015

    I've been on the 28 day challenge for almost 3 weeks. I had lost 15 pounds prior to this program and I was looking for something that would keep me on track. I have lost another 6 pounds in under 3 weeks. I want to lose 1.5 to 2 pounds per week so right on my goal. Definitely helping with my eating habits. I have the Hydrate/Energy drink and the lean life on the way to work and then have a meal replacement shake for breakfast. Eat a light lunch of chicken and veggies. Afternoon snack is a meal replacement shake (helps with workouts when I get home). Supper is chicken or venison, rice and veggies. The taste of the product is better then others I have tried. I still have plenty of energy to run and lift weights (actually more energy then before I started taking the product). I ordered additional product so I could continue on with the program.

  5. Works Great !!

    Give it a try you wouldn't be sorry !!!

  6. Phenomenal products!

    Posted by Ktreme on 28th Apr 2015

    Wilderness Athlete makes some of the best products on the market!! This is coming from someone who has been training for years looking for just the right products to amplify performance. I am a Firefighter/Paramedic who hunts, fishes, and does multiple half marathons and triathlons yearly. I keep myself extremely busy day in and day out and cannot run low on energy, fuel or focus. These products will make you feel your best when combined with great eating habits. The Hydrate and Recover has got to be one of my favorite products. All of them taste great. I ordered the 28 day challenge on special just to give WA a try. I am hooked and will be ordering it for years to come. I set new PR's for myself while on the challenge. Trimmed over 6lbs and 12 total inches while feeding and maintaining muscle. The products are really beneficial when it comes to recovery time. They really help your cells get the right amino acids at the right time to reduce inflammation and speed up recovery. Great stuff!! Finally a quality product for the all around working athlete!

  8. Life Changing

    Posted by Josh on 24th Apr 2015

    I started with the 28 day challenge on
    Feb 1 and lost 17 pounds. I have continued to follow the good eating habits it created as well as the hydrate/recovery and energy/focus with the green infusion and have lost a total of 30 pounds. It truly has changed my life in a positive way.

  9. The real deal

    Posted by Unknown on 24th Apr 2015

    Had been hovering 10-15 pounds over weight for a few years, couldn't get it to come off. When I drew my bull tag this year I said I was gonna lose it. Just completed my 28th day and I was able to lose 18 pounds using the 28 day challenge. This was just by the shakes and supplements, a good diet, and a couple days of light cardio a week. Thanks Wilderness Athlete!
