Through the various flash sales I've picked up the 1 barbell blaze, harder to kill, and foundations programs. For $7usd you cannot go wrong. 1 barbell blaze was the first eo3 program I did and it was a good quick shot of strength and conditioning. Foundations is hard and heavy. I've tried to work through foundations twice and have stalled both times. I picked up the harder to kill program last time it was on flash sale and haven't tried it yet. It looks like a 6 week version of what Jerred programs for the garage gym athlete subscribers. Probably more to give you a sample and if you like it you'll subscribe. A mix of max strength and conditioning. He actually posted a video this morning of how he comes up with his strength/conditioning blend.
My thought. If you have a chance to pick up any of these programs for $7 you should do it. Even if you don't plan on using them right away. Gives you the option to switch it up and try something different short term. And since they've changed some of the subscribing options you can't access the extra programs unless you buy it or subscribe. I like having it in my back pocket as something I can pull out and run through if I ever get bored.
