Thruster Double Under

Warmup:
4x5 knees to elbows
4x5 ring dips
4x5 squats
4x5 back extensions
4x5 situps

WOD: "Thruster Double Under"
5 rounds for time of:

• 21 thrusters (75#)

Time 21:16 as Rx

I had to mostly single jump ropes because I am not proficient at double unders yet, but I did sneak in a few every now and then.
