Spin bikes earn their reputation in 45 minutes. High-intensity intervals, sweat dripping off the bars, a sustained 80–90 rpm cadence with the resistance dial cranked. That's the test, and it's the test most home bikes fail.
The 15 best power rack exercises are: back squat, front squat, pin squat, Romanian deadlift, rack pull, bench press, overhead press, floor press, pull-up, Pendlay row, inverted row, dead-stop deadlift, isometric mid-thigh pull, hanging leg raise, and anchored banded row. A power rack turns a barbell, a couple of plates and an empty corner of your garage into a complete strength training system.
