I’ve had great success with my wife, making her some Cross Fit style WOD’s.
We do have a cross trainer in the home gym, so I’m using that as well.
Have her do a warmup with lots of mobility work and moving around. Something like 20 - 30 minutes. With something to bring the heartbeat up. Make it simple and easy to do.
Then make up some WOD’s that’ll take about 10 - 15 minutes some a bit shorter some a bit longer.
It could be 5 push up, 5 DB row, 5 DB press, 5 burpees and 10 rounds.
Our house has 2 stairways so it could be hiptrusters, plank, lat raise, 1 x from basement to 1’st floor and back for 5 - 7 rounds.
It’s just your imagination that sets the limit.
Have her time the WOD, and write it down when finished. A time to beat.
Make her 2 or 3 for a start. Then every 5 days or so make up a new one, give them some fancy names.
Do it every other day for the first week, second week 2 days on 1 day off.
Track her food with fitness pal or similar, she should weigh herself every morning and track it too.
Remember every weightloss is done in the kitchen. NOT the gym.
Watch Alan Thralls video how to avoid dad bod… ditch the and’s and eat an apple not a pizza.
The last piece of advice would be take her out for walks, long walks. Not necessarily fast walks, a nice stroll were you’re talking and laughing is great.
She must do something she likes, that she finds is fun and something she would do because she finds she can do it.
After the wedding you could introduce some serious lifting, but for starters it should be something fun and challenging and 5x5 is not.
Have fun Nutty
