I'm a personal training that needs a simple logo for my website and also cloths..

Hi
I have an online fitness business that focuses on personal training.
I would like a simple but professional logo for my site, something that makes it clear it's to do with fitness.
Ideas:
1: The writing Solid Gainz with a measuring tape underneath in some form.

2: I was thinking something to do with mountains to relate to my name Solid Gainz "solid as a rock"

3: Solid Gainz with a nice font and on of Z we can put the outline of a men and woman doing a weight move.

Also willing to listen to ideas too
