Apex Hills Treadmill

Have any of you all don’t Apex Hills on a treadmill? I currently don’t have a KB I can just take to a hill. So I been doing 10% incline for 35 seconds and then jumping off to do 12x 53lbs KB swings, with a 1-2 min rest in between sets.

I’m also using the treadmill to get my legs use to moving fast again after all the LSS runs.

Does that sound like it could work as a good alternative?
