Endurance vs. Stamina
Brian and Cindy both test out different modifications for the Double-Under.
Although Cardiovascular/respiratory Endurance may sound the same as Stamina, they are actually very different markers of fitness. Here are each of their definitions:
Cardio Endurance - The ability of body systems to gather, process, and deliver oxygen.
Stamina - The ability of body systems to process, deliver, store, and utilize energy.
Here is an easy way to differentiate between the two. If during a workout, your breathing becomes extremely fast and shallow while your lips and face begin to turn blue, that is failure of your Cardiovascular/respiratory endurance to provide enough oxygen to your body. If during a workout, the weight that was once light starts to become harder and harder to lift and your muscles are begining to fatigue, then that is a failure of your Stamina to deliver and utilize energy to keep your muscles going.
Understand the difference? If not, let me know and we can always put you though a "demonstration" that will make it very clear ;)

I finally made it back today after being sick and having my 4 wisdom teeth pulled. It feels like I haven't worked out in forever and I've really missed it. It felt good to work out again.

Great to have you back Luke!
WOD: 65-85(F)-85-85-85

Double unders really slowed me down in the first/second rounds of Annie, and need a faster pace with situps. But happy to get one in as Rx'd =)
