Fat loss will largely come down to her diet Bradders. I roughly follow a protein dense, lower carb routine with re-feed days on the weekends. But everyones body responds differently. Calorie deficit with the right macro balance will get that fat moving.
Jen's at a perfect starting point for weight training, I started at 94kgs & I wish I'd started sooner!
I need to drag her to boxing
Best thing, hands down, I've ever done.
My advice is to get the diet right first. Spend some time playing with numbers until she's shedding weight off the scales each week (the numbers shes dropping are less important, they all add up!)
Then to start on a simple weights program. She'll see some beautiful newbie muscle gains while she is having fat loss too. Form is paramount, the weight lifted at the very beginning is irrelevant, she will get stronger as time goes on. Her priority is fat loss for the time being.
HIIT anything is ok. 10-15 minutes a day of hill sprints, interval training on the rowing machine/xtrainer/treadmill, skipping whatever (Interval rowing/xtrainer or boxing would be good for Jen, given her shitty knee). She should count that as purposeful exercise & keep it brief so it doesn't feel overwhelming. Bike rides, treks, stair climbing & whatever else you two crazies do, are just incidental additional activity. lol
I found this paramount in my approach psychologically, so things could still remain fun without me feeling like I HAD to do them.
As you will note from my log, 18 months on, I can't actually ever rest now. lol The rush of exercise & the way your body rewards you with tangible results, is very addictive
1. Right Diet
2. Simple weights Program
3. Simple HIIT approach
4. Incidental additional exercise factored in
The hardest part, as you know & I know, is just starting. Everything else, will come.
Good luck Jen
