the issue is she does nothing other than what she shows on the gram, 45 mins of a class where we've repeatedly seen her heart rate do
duck all, team classes where she comes last, strolling around the park, shocked and/or struggling to hit 10k steps.
Anything she does is that, and that alone, she's not walking anywhere, shes not scrubbing the house, she's also not working.
Your body needs the usual daily movement called NEAT( Non-exercise activity thermogenesis ) to keep ticking over, the 45 mins/1hour a day doesn't sustain you, she'd be better off going for a proper walk daily, or you know...getting out of bed or off the couch...
