So I tried a different variation of the 5×10 endurance sets this week.  I did sets of 5 chin ups and 10 dips.  Difficulty wise it was definitely a level above last week since I can definitely crank push ups easier than dips.  I wound up doing 20 sets of the circuit in a little over 27 minutes (a slower pace than last week).  That worked out to 100 chin ups and 200 dips, a total of 300 reps.

I am working in a sleep deficit so I went into it feeling substantially less than 100%. I seriously need a nap right now.

I will have to see if I can come up with any other combos that work out well in these type of sets.
