If you are looking for strength and conditioning along the lines of the Jon Engum program that
@J Petersen pointed out, but with a barbell, try a web search on this
Bryce Lane 50/20
Briefly summarized: Take a compound movement (BP, DL, SQ, C&P) and you do 50 reps in the space of 20 minutes. Barbell is the usual implement of choice, but you could do this with a sandbag, and you could even do this with double kettlebells.
Word to the wise - start gradually, don't hurt yourself doing too much too soon, and remember that bad form is _never_ an option.
A good guideline is to start with either a 10RM weight or 75% 1RM. NB: According to many sources, those two should work out to be about the same weight.
You can begin by doing this twice a week, and you can eventually add a second movement and end up doing this four times per week provided you don't drive yourself into overtraining by doing so. You could also pick different compound exercises and do each one once/week - more variety of training, less improvement of skill at each lift due to less practice.
You may do other training alongside your 50/20, again if it doesn't push you into overtraining.
For a strength focus, consider starting with a lift you can get only 30 reps in 20 minutes and building up to 50. For more conditioning, start with 50 reps and work up to 100.
Compare this to Jon's program, which is 100 reps in 10 minutes - The 50/20 is more of a strength focus because you're moving more weight for fewer reps, but you will certainly get some conditioning, and without a doubt, the 50/20 is a good way to add meat to your bones provided you eat enough and sleep enough.
NB: If conditioning, particularly for a sport or martial art is your goal, I'd stick with Jon's recommendation.
