How do you figure ?

When I moved and no longer had a lifting partner I used a power rack to do military presses and set the safeties on the sides of the rack. Granted you can't do forced reps and stuff but the oh s#*t clause is definitely still there. Besides that just ask someone you trust to spot you I am lucky enough to have an ex Jacksonville Jaguar who hangs out in my gym quite often.

There will be no problem using the smith.
I don't do straight bar press.
I ONLY use DB and Smith machine.

Go ONLY AS DEEP AS CHIN
and ONLY AS HIGH AS 4in ABOVE HEAD.

The Smith movement give near perfect form.
The ISOLATION. comes from the depth / height range of motion listed above.

You may also do your upright rows on the smith.
continue your lateral raises and alternate press with DB press EOW.
Good luck.
