Cardio is not recommended in Phase 1 because you simply are not eating enough calories to support vigorous exercise. If a person was very active prior to P1, their body can tolerate a bit more and they could potentially resume MILD exercise after about week 3 with an additional packet on workout days.
Strength training does not raise your heart rate in the same way or burn calories at the same intensity as cardio, and can actually be good on P1 by helping to increase lean muscle mass. The trade off is that any exercise you add has the potential to slow down losses a bit if you only go by what the scale says. But building lean muscle can improve inches lost, and lean muscle %.
Any exercise should not be added into your routine until after week 3, once your body has settled into ketosis.
