Help with extreme tight bicep tendons

I just finished the fundamentals course and really enjoyed it so far.
My main problem are extreme tight biceps tendons as Coach Sommer mentioned in the podcast.
They feel like tightropes and my upper arms/front delts hurt after I have done push ups, dips, pull ups etc.

I really don't know what to do about this problem since the crap exercise proofed this issue but has not solved it yet.

Any help is greatly appreciated

Coach Sommer puts a large premium on shoulder extension, so you'll find mobility drills in many of the courses to help with this.

The Thoracic Bridge course has the most focused selection, but the HS One and Foundations courses also have some real gold.

In any case, it took more than a month for the tightness to develop, it's going to take some to to improve. And even then, it's an ongoing battle of maintenance to keep the mobility you gain.

The thoracic bridge exercises are great for improving shoulder extension.
