Figuring out what sort of lighting will be used

I was really happy with the images that I took on the square format especially the profile ones. The main inspiration behind these was the work of Irving Penn and Jeanloup Sieff so I think it would be a good idea to apply the things I’ve learnt to the gym photos I’m planning on doing. The contrasty light would help emphasise muscle definition and help distract the viewer from seeing the garage clutter in the background of my ‘garage gym’.
