Shoulder Press and Back extensions 080617

Did a weird mix of Pack and Puppies.

One round of:
21 reps 35kg Shoulder Press,
21 Good mornings holding a 20kg plate

Four rounds of:
21 reps 25kg Shoulder Press,
21 Good mornings holding a 20kg plate

Pack weight was too heavy so dropped it after the first round.
Then I messed up the counting and only did 5 rounds.

Still obviously not the correct load for my weak shoulders, that time should be much lower.
Seven rounds for time of:
21 reps 35kg Shoulder Press,
21 Good mornings holding a 20kg plate
