Works for me!
This method really works for me, can do anytime and anywhere. This new app is great, it adds so much diversity to the programme - my worst enemy is boredom! I got to know this programme when my regular gym was closed for works, and I never went back.. I travel a lot and have actually done some pull ups under the hotel bath room sink. No need to take extra gear in the suitcase either.
