military bootcamp

Options
received an offer email of 6 sessions for £24 at the park 5 minutes from me and wondered what people thought of them

i've lost over 10 stone in the past 30 months - 6 in round 1 and 6 in round 2 (gained 2 back over 18 months)
i'm not too saggy and now want to work a bit more

thoughts please on if it's worth it
