So, I noticed the consensus around here is to post logs weekly.
After day 1 (posted above) I tried to do something on the in between days. Where I live, winter's coming and I don't have the gear to do outdoor cardio (e.g. run), but I do have Kettlebells (16 and 24Kg) and some dumbells, so...
"Off" day 1 - Tabata Kettlebell Swings (two handed 16Kg KB) - Swings per active round: 9 min, 12 Max. 5 min ab workout.
Day 2 (level 1)- 8:46. Again, subbed 3x jumping pull-ups
Off day 2 - Tabata Kettlebell Swings (same as above) - 8 min, 10 max. 3x10 KB clean and press (16Kg KB).
Day 3 (level 1) - 4:07. Broken down to pull-ups 15, 8, 7 - pushups 15, 6 - squats 11, 10.
Overall, I feel pretty good. My lower back is sore (was before I started this week), so I have to warm up more than if it was healthy, but I was able to complete the workouts without causing any damage. I was gasping for breath pretty hard at the end of Day 2 and Day 3, but again, never at risk of hurting myself, so win.
For future weeks I plan to do a Off day 3 workout, but I'll be traveling tomorrow and next weekend. Next week I'll be away form home and wont have access to a pull-up bar. I'll be checking around for a substitute, but if not, are there any decent bodyweight subs I can use for the week? Burpees?
