Full day of activity finishing with some misery

AM Practice - 4 mile ride, push-ups, 3 min abs

At school - walked almost 800 meters and then ran almost 800 meters

PM Work out
Leg burn - supposed to do more but with my last few days I struggled here.  Ended up ice bathing after the workout at home.

Different set up here - Daniel design
10 Back Squats (deep) @ 135lbs
10 Left leg box @ 24" single leg squats with foot on box holding 45lbs KB in left hand straight along side.
10 Right leg box @ 24" single leg squats with foot on box holding 45lbs KB in left hand straight along side.
10 Front Squats (A To G) @ 135lbs
10 Right leg box @ 24" single leg squats with foot on box holding 45lbs KB in right hand straight along side.
10 Left leg box @ 24" single leg squats with foot on box holding 45lbs KB in left hand straight along side.
Repeat this cycle 4 times.  On the single leg squats on the box outside hand was supporting holding rack.

I was beat by the end of this.  Sweating like crazy.  Crazy thing was I got the last 2 rounds done faster than the first 2 rounds.
This is a terrible description of the box single leg weighted squat but best I have.
