Reno is a strength circuit that bets on holds over reps: 5 squats, a 20-count squat hold, 5 more squats, 2 push-ups, a 20-count plank hold, 2 more push-ups, and 20 bicep extensions to close. The rep counts look like small change until you notice the holds are twice as long as anywhere else on the usual card.

The 20-count holds are the house edge here, and they change what the modest rep counts actually cost. Five squats are a warm-up; five squats after 20 seconds parked at the bottom of one are a different transaction entirely, because the isometric drains the exact fibers the next set needs. The push-up block plays the same hand - two reps in, 20 seconds of plank with your shoulders and core paying interest the whole time, two reps out. This is time under tension doing the work that volume usually does: the muscle doesn't count reps, it counts seconds of effort, and this circuit quietly stacks more of them than a set of twenty would. The 20 bicep extensions at the end are the one high-volume station, self-resisted and honest - you get out exactly the tension you put in.

Hold the squat at working depth, thighs near parallel, weight in your heels - hovering an inch down doesn't pay out. In the plank hold, push the floor away and keep your body one straight line from head to heels for the full count. Push-ups run chest-low and full range, both before and after the hold. In bicep extensions, clench hard and move like you're fighting through water.

What happens in the hold stays in the hold - right up until the next set of reps collects.

Make it Harder: Stretch both holds to a 30-count.

Make it Easier: Take the plank hold and push-ups from your knees, keeping the full 20-count.
