This simple mass gain plan by Ben Greenfield is designed for a skinny, lean or thin male or female triathlete to add lean muscle and mass while simultaneously building coordination, speed and power. It is perfect for the off-season, or for any endurance athlete who simply needs to get stronger!

The plan includes:

-Detailed instructions for each day of the week, with workouts, exercises, meals, recipes and zero guesswork - you just follow the simple layout...

-See the entire plan in full, get a daily email with your training and meal information and sync your workouts with your personal calendar (it’s harder to skip a workout when it’s staring you in the face!)...

-The full ability to print the program, have your workouts delivered to your phone, computer or tablet, and a free app for iPhone, iPad, Android devices and other web-enabled mobile devices...

-Plan ahead for workouts and meals to stay organized and avoid pitfalls. You can even print a grocery list to help you stay on target while at the grocery store, and see valuable metrics like calorie counters, carbohydrate:fat:protein breakdown and all dietary details...

-View your workout information however you want. Color code workouts, easily search through all your logs or even print out a copy for your fridge. You get to use a system that works for YOU.

-The ability to share workouts or meals with friends on Facebook and Twitter for extra motivation or accountability. Let your friends encourage you along your journey or inspire someone else to come along.

-Everything you need to make simple to track all your training, nutrition and metrics like weight and sleep with charts to monitor your fitness, muscle gain and performance trends as they change over time...

The plan can be customized to last as few as 6 weeks or as long as 12 weeks, depending on the amount of time you'd like to use for your mass gain. The entire program is based off the principles in the book "Mass Made Simple" by Dan John (which is a good complementary book for this program - go to http://goo.gl/Wm8iL3 to download it).

And there's a bonus too!

Every month, Ben Greenfield is sitting down and writing a check that includes a full refund of your plan purchase plus a $100 bonus if you post before/after photos to your blog or Facebook and they are ranked as the best before/after photos for the month.

So if you take a front photo and a side photo before starting this plan, then log your progress and muscle gain, and continue to add front and side photos each month, you can actually get paid for using this plan! All you need to do is post the link to your progress on Ben Greenfield's Facebook page, and be sure to mention that you're using this plan (just link to this plan at http://goo.gl/pO306h)!

If you're a skinny endurance athlete who wants to bulk up in a fast and healthy way without destroying your body or overtraining, then this plan is for you.
