I hear ya man. I have 3 kids, a dog, a mini pot bellied pig, a job at a power plant where I work 12 hour shifts and flip flop between day shifts and nights. Those 3 kids have 'activities' the wife has me do shit etc. We all have the same 24 hours in a day. WE must figure out how to fit training in IF it's important to us. YES I feel like a sack of smashed assholes 1/2 the time but I somehow make shit happen, to some degree. Some days the heaviest thing I lift is my ass off the couch. Think on that for a min....
Gym memberships are overrated most times. You have to listen to shit music, put up with all the doosh bags doing dumb shit and most box gyms are not PL friendly, at least not for long anyways.
You don't need tons of money to be a bad ass. Go get an old pick up truck tire from a tire place. They will give you all you want for free. Then put an eye bolt on the side wall / tread. Attach a rope to it and you got an instant dragging sled. Beat it with a sledge hammer. 2-3 min of whooping that tires ass and you'll be gassed. Find weight plates / bars at Yard sales / craigslist / play it again sports etc. Or you can go old school like my buddies dad from Long Island, go steal manhole covers and use for weights lol ( just kidding!) get a "D-Handle" and a length of small chain and a caribiner. MAke a makeshift kettle bell with a few 10# plates and the chain / handle. Now you can do kettle bell swings, which will help that deadlift.
