Ok, so my gym has decided to close for 3 months, undergo a massive refurbishment. Do away with all the unnecessary bullshit to cut costs (steam rooms, saunas, other unused malarky) and change it's persona. This seems like a good idea, but has left me with 12 weeks of time I can't get into a gym. Another gym is also opening in 12 weeks time so it seems that there will be a nice choice in 12 weeks but nothing to keep me going until. I've made some good progress recently and don't want to throw it all away.
I did a brief search, but didn't really turn up anything. I have an old pullup bar and know I can do pushups and tricep dips off a chair or something and can go for a run ouside (gosh!). I was wondering if anyone knows of any routines that can be done without any equipment, that will tide me over. I'm not expecting to make any massive gains, if any (is it possible?) but I would like some sort of damage control. I literally have ZERO money to spend on any sort of equipment. If anyone could help me out with any routines they know of I would be GREATLY appreciative!
TL;DR: 12 weeks of no gym, need routine(s) to tide me over. Thanks
