“Been working out since 1975. The Isomax has taken center stage. The combination of convenient, very effective isometrics and seeing the amount of force generated on each rep is phenomenal. Dragon Door's innovations are a godsend. I'm 70 and the strongest I have ever been.”

In the real world, most Boomers are not pressing 32 K kettlebells and the video shows actual boomers of different ability.
