Correct spelling is Kettlebell, kettlebells. Or just using its original russian name Girya.
Here are few good articles which should give you a some idea about what to do with them.
My program is as follows:
10x Right arm swings
10x Left Arm swings
10x Double arm swings
10x Right arm clean and press
10x Left arm clean and press
10x Right arm bent press
10x Right arm bent press
10x Alternating squats
10x *Double arm press, squat and rollback
10x Hindu pushups
30x Hindu squats
I do 4 rounds like this with total time in around 30min.
*I don't know name for this move, but it is basically just as follows: Hold your kettlebell with both hands, curl to chest and then press over head. Lower it using the same route and then squat and roll with your back, then stand up again with hands straight kettlebell between your legs.
I have been using 10kg(22lbs) kettlebell so far to correctly learn the moves. But today I'm going to post office to pick up heavier one, 17kg(37lbs).
Up till now I have been doing that program three times a week (mon-wed-fri). But Now that I have heavier one as well, Im going to change it a bit.
Mondays: 6 repeats per set, 4 rounds with 37lbs kettlebell
Wednesdays: 10 repeats per set, 4 rounds with 22lbs kettlebell
Friday: 20 repeats per set, 2 rounds with 22lbs kettlebell
In about month or so, I'll consider increasing weekly excercises to 5.
In addition of those I currently stretch every night for 30min. I haven't ever really liked stretching, and because of that especially my hips have been very tight. Now I have decided to do something about it. Should see some results before end of summer.
I'm pretty short, only 5'8" and 193lbs so I think I need to bring my weight down to 185ish. Have some bellyflab I need to get rid off.
