Body by vi and exercise?

ahind5

Ok so I'm needing advice! I have been on the vi shakes for 2 weeks. My husband said I need to exercise or I'm going to gain weight. So I read some tips but nothing has helped! I plan on waking early to do my exercise (before my kids wake) so my question is do I have my shake before or after? Than when should I have some vi trim? Anyone who could help please do!

Thanks!
