@vivicrocodile - looks like you need the pre-beginners' prep, namely:
Lucy Wyndham Read Thighs & Glutes
Rebecca Louise Best Abs
Rebecca Louise Ageless Arms (using decent, i.e. challenging weights)
Bowflex 3-minute plank
Do the above every second day.
Do a 30-40 minute Growingannanas HIT with weights on alternate days.
Plus the Bowflex 3-minute plank.
Do the above for at least a 2-4 weeks.
Then try Caroline's EPIC Beginners again.
But make sure you do the Bowflex 3-minute plank every day.
Very important this.
