Normally 60 minutes, but everything depends on your necessities.

The session inlcudes the warm up and the cool down/stretchng phase.

No, I work at customers' place (house, office etc...) or outdoor. I'm not affiliated to any gym.

Absolutely not. I will design the workout according to the available space.

No. I usually work bodyweight or with a light equipment* that I personally bring. Don't worry about that.

*I personally desinfect and clean all the equipment before and after a session.
