One (Drop) Set Max to Failure

Diamond push-ups followed immediately by regular pushups:  45
Pull-ups followed immediately by rows:  36 (20 pull-ups!)
Assisted pistol squat to "deadlift" to squat:  35
Dip to bench dip:  46 (28 dips!)

Hard Work Distilled - Mini Drop Sets to Failure

I decided to take the hard work idea and push it further in difficulty and intensity but drop back on the volume.  This has really paid off.  I decided to take a core difficult exercise in the Big Four and do a set to failure or almost failure and then "drop set" that with a less difficult exercise in the same group.  I have been quite surprised at my numbers and enjoy the intensity combined with low volume, so I don't feel like I need to be doing this all day long.  If you go to failure, you really need to repeat less often.  Here's my max:

Diamond to regular push up- 36+14=50
Pull up to doorway row - 30 (10 reg, 10 neutral, 10 chin)+20=50
Deadlift (alternating) to regular squat - 22+23=45
Dips to bench dips - 33+19=52

Honestly, I never thought I'd do a set of 30 pullups (pretty decent form, degrading at the end) or 33 dips.

I think I may be on to something here.
