In order to get good suggestions you should draw a floorplan, preferably on graph paper so the commenters can tell what the dimensions of the space are. How much space do you want for your exercise equipment?

Oh sorry I'm new here. The whole space is 750sq ft. I only have a few small things for the gym area.

No one can provide useful suggestions without the measurements of the space and the equipment/furniture. Why not just move stuff around and see what works?

When you provide that floorplan for the whole basement, note electrical locations too, and the treadmill probably needs to be on a 20amp circuit (or a 15amp that is not loaded), and if you want a tv how far from one or if you can add a receptacle up high. Note size needed for the rubber mat area for free weights if you also do stretching/yoga. Walls available for mirror. Soffits that you might hit your head on the cycle/inclining treadmill.

In the area where you'll have the couch and tv, ceiling lighting is not optimal. Much better will be a table lamp or wall sconce in each corner at chest height. If not done already, you may want to get an electrician to put the different basement zones on different ceiling light switches.
