Hi Schnebit,
My 2c would be to start on just doings 7 reps of each exercise to get into the rythm of the movement. Then you can up the reps to 14, 21 or as your body dictates.
Think of this as playing the long game - one week here or there of low reps is nothing when you think that the idea is that you do these exercises, in one form or another, for the rest of your life...
I recently took a couple of weeks off to rest up my elbow. When I started up again I did a week of just 7 reps of each exercise in my normal routine. The next week I stuck to just 14 reps. Then the following week 7 -14 and then 7, 14, 21 or until the 14 minute timer goes PING!
I do my shovelgloving at 06:15-06:29 in the morning, so I never vary the routine. The originality and creativity nodes of my brain don't come online until much later and I find this is easier to do, rather than thinking about what to do next. Before you know it, you are in a lather and the timer is calling time.
I hope this helps - but the best thing of all is to do what you enjoy. There are no rules!
Good luck, and happy shovelgloving!
Rich
PS For the record I do the following:
Shovel: 7-21-14
Churn butter:7-21-14
Stoke the oven:7-21-14
Flip the lever:7-7-7
Side lifts:7-21-14
Hoist the Sack:0-21-0
I also do some post exercise stretches to loosen my hamstrings and lower back.
