I REALLY needed a good workout today, and our 15 minute "finisher" at the end of group training this morning certainly provided that. He called it a "modified Cougar"

15 KB swings
10 Goblet Squats
10 TRX Rows
10 Pushups

15 KB Swings
9 each of the 3 exercises
15 Swings
8 each...etc...down to 1 with 15 swings between each set.

I DID get them all in 15 minutes and even beat my team-mate. Done...and I was DONE by the end. Finishing first was a surprise to me, but he did have a heavier kettlebell to swing than I did. That does have an effect at some point - we did a LOT of swings!
