"Vacation workout" sounds like you are obsessed and should take a break. In my case, I don't think I'm obsessed, I just wanted to keep feeling good and be free to eat a little extra and enjoy myself on vacation. I've worked hard for the last two years to get my waist down to a healthy size. One week wouldn't necessarily blow up all that work, but keeping my metabolism running each day would help.
I finished my workout before my kids woke up. The days were filled with swimming, sight-seeing, and other play.
This is what I did:
Ladders (1,2,3,4,5,4,3,2,1 or 2,4,6,8,6,4,2 of the main four exercises)
- Split squat
- Lying Back Press or Lying Scapular Press (an isometric exercise)
- Single-leg Glute Bridge
2 sets of RKC Isometric Plank for 10 seconds
The only equipment this required was a dining chair for the Glute Bridges. The whole workout took 20 minutes. I felt good on vacation and think it was worth it.
