Well, my goals are to be able tu lift, push, pull, manipulate heavy or large objects, and to get my atleticysm back.
I would recommend a basic strength program like a 5x5 program (plenty of free examples on the internet) or Starting Strength (an actual book and program). Please dont confuse "strength" program with "bodybuilding" program. (more on that below). Anita mentioned Stronglifts, which is a good one and can be found online for free.
For "athletic" improvement, since I dont know what specfic attributes that you want to improve on (speed, agility, quickness, hand-eye coordination), I would make the general suggestion that you try to do some "dot" drills (check you tube) or buy a cheap agility ladder ($20 will get you a decent one on ebay) and work some of those drills.
Because you said you want to improve strength and not size, I pointed out that you may not want to do a bodybuilding routine. Strength routines utilize a LOT of the same movements as a bodybuilding routine, but with a different amount of weight and rep/set scheme.
-Bodybuilding routines focus on myofibrllar growth and use about half of your maximum load for 8-12 reps per set. This obviously will allow you to imcrease strength to a point as well, but is also very much about muscular size.
-Strength training programs will have you use close to your maximal load for fewer reps (6 reps max) and focus on sarcoplasmic growth. Obviously, either of these routines require the use of resistance, typically barbells and dumbbells.
If you cannot join a gym or have no access to barbells/dumbbells, then I suggest that you make a sandbag or two. You can make these with very little cost, store them almost anywhere (anywhere a typical duffle bag can fit) and they are great for increasing strength. If you decide to go this route, PM me and I will send you a link with instructions to making one cheap (with various options for what to fill it with). The first one I ever made was with a duffle bag I got at Goodwill ($5), some strong contractor grade trash bags ($5) and dirt (free).
