I definitely need a microphone as somewhat the focal point as this podcast is mostly an audio podcast. So when people listen on youtube I need the logo to stand out because that is what they will see on the screen. If you could incorporate something fitness related with the microphone that is great as well.

I also would like some designs WITHOUT the word podcast in it as well so I can see how that looks. 

Try These 3 examples:
-The Weekly Supplement
-The Weekly Supplement Podcast
-The Weekly Supplement with David Nubia

Colors- Preferably any of the following but not all 3 together (Red, Green or Blue) 

Excellent service and always was able to fix any issue I had or needed to be changed. Will definitely be in touch when it comes to any other branding needs.
