WOD: 8/3/17

Conditioning
AMRAP 4×4, with 4 min rest between each
1) 400m Buy-In, then max DUs

3) 400m Buy-In, then max Wall Balls
4) 400m Buy-In, then max Cal Row

Intended Stimulus:  this is interval work.  Interval work is effective because of the rapid increase/decrease fluctuations in heart rate.  You should aim for a true maximum effort in each of the work intervals.  The rest intervals should be long enough for your heart rate to decrease significantly.  Work at a fast pace as if the immediate four minute work interval is the only focus of the workout,  and without regard for previous or subsequent work intervals.
