Mobile Personal Trainer - Brand Logo

As a start up self-employed mobile personal trainer, I am looking to create a bit of identity with a brand logo. I mainly need the logo for my 'Personal Trainer' work t-shirts to be displayed on. I'll also need it potential for social media/websites in time. I'm looking for something that looks professional whilst also having some character. Additionally, I want it to stay within the parameters of the line of work I'm in. I've played around with a few ideas such as a wolf or lightning bolt with my name alongside the logo. I think having my name attached to the logo is essential. Also things like Kettlebells or a reference to the fact I am a mobile PT meaning I come to clients homes to train them could be a good idea for the logo. I'll attach below a few logo ideas I'd be playing around with on Fiverr. (Also, don't want a cartoon design)
