Mol’ there’s a whole load of body weight typr exercises available on youtube, starting from that hindu push up vid I posted. I usually do mine when I decide to go for a quick run round the park. Find a hill or a place with trees for markers – or take yer own markers and set up two or three shuttle runs at 20m intervals.
sprint /burpees
sprint /press ups
sprint sit ups
sprint back
rest in plank position 30 seconds repeat
that kind thing, add a variety of exercises and a vary the running etc and you’ll get miles fitter than you will using a poxy hotel gym machine.
