What exercises/activities do you do to keep fit?

Walking has ALWAYS helped me to keep myself moving.
( Because constant movement like walking, helps a lot )

I jog like once a day and keep a steady and comfortable pace.
( The key is to always move and less stops )

For weights, I just lift weights to relieve physical stress and feel better.
( I just do it to stay easy, not build any extreme muscles, but it does naturally )

I dance with my mp3 plugged into my ears.
( Sometimes it's better to just have fun moving )

Laughing ALOT!!!
( It shakes ALL your muscles and that's a good thing )

Ha...gettin yo shake weight on? (jk)

I like to do a 1,000 jumping jacks,I run two miles around the city, I run around the park with excess body weights on my person, I do ten types of sit-ups one hundred times along with total gym reps, squat lifts reps, hang clean reps, bench press reps(I do isometrics good for building additional strength before doing reps), I do zumba, I have a stationary bike I stay on for about a half an hour, I hit a punching bag with punches, kicks, knees, and elbows(my head also) a hundred times, and I like to consume over 1,000 calories so I can burn off chemical energy while training and afterwards...

Lol, JK. [size=2]Also, I'm not white..[/h]

Ha! Well to be on topic I like to hit myself in the stomach one hundred time with a wooden and metal bat to help toughen up my abs...Hey if you gonna deliver a hit you got to learn how to take one.

Damn, I'm pretty sure da russian army does that. R u tank?

Hmm...Kind of? I mean I have muscle but I have a pretty high level of body fat.
It may sound silly to others but I am trying to find a good ratio of muscle and fat.

Muscle weigh more yet it is more aerodynamic; fat weighs less yet it can cause many problems during strenous activities. I want the benefits of both.

Too stay on topic again I do alot of flexibility training as well.
Remember when Bruce Lee on Way of Dragon before he was to fight Chuck Norris. He put his legs together bent down and made his head touch his knees?

I can do that...I can also hold a chinese split, an american split, and a back bend.

Mountain cycling, weights, push ups, crunches, some yoga, jogging and the odd sport or two. Also want to start ninjutsu and muay thai

Rock climbing used to get the job done for me. Kept my arms wonderfully tone and my hands constantly torn up.
Aside from that it was just general fitness- running and light weights.

My friends and I go night biking a few times every week.
It's crazy.

I also go to the gym for a good workout.

Been trying to run around the park every other day.
Push-ups and other ab work-outs everyday
And I want to do kendo cuz it just sounds fun to me and I want to kick my friend's ass at it. =w=

I'm lazy as hell and eat alot but still skinny for some odd reason?
As for workouts, I usually give my Ps3 a break and listen to music while walking around my apartment (inside) for an hour with the T.V on. .

Used to climb alot, which i don't do anymore because of an injury in my wrists. Now i run 5 times a week and lift some weigths at home.

I have weightlifting at least 4 times a week with some cardio mixed in here and there. I also have practice 4-5 times a week as well. Its all mostly mandatory for my sport but its keeping me in shape, and its fun too!

I practise Karate and do some weighlifting, Situps and Pushups at home

USMC physical training which may involve any combination of the following.

Weekdays 1 hour of P.T. involving

Pyramids, pull ups, froggers, lunges, various sprinting exercises, up to 2 miles of running. Then finally a variety of exercises picked from the list below. Though exceptions have occurred where the entire P.T. was a 5 mile run.

Saturdays up to 5 hours involving

Initial Strength Test (Done only on Saturdays) which involves a max set of pull ups, crunches and a timed 1.5 mile run.

A circuit involving up to 5 of the following for a duration of 2 minutes each repeating for 2 hours hours total.

Push ups, Burpees, Froggers, lunges, suicide runs (involving a parking lot and every line on every parking stall), ammo can lifts, crunches w/ 20lb medicine ball, flutter/scissor kicks, uphill sprints, weighted sprints (30lb ammo can or 20lb truck tire), fireman carry's, squats, squat-thrusts (a.k.a "monkey fuckers), Kettle bell swings w/ 20lb kettle bell, side straddle hops.

Another hour of training involving lots of sprinting (usually up a hill)

An additional 3-5 mile "motivation run" sometimes calling cadence.

There are exceptions where after the IST we do something such as a 3 mile run (carrying weights) stopping every mile to do 10 minutes of high intensity exercises or even carrying people on stretchers up the local mountain (1,808 ft) while those not on the stretchers carry weights.

Tae Kwon Do training 4 times a week
Every evening I do weight training until I can't even get up anymore.
Every morning I do legstretches and train my splits.
When there's nice weather, whenever I need to go out, I sprint to my destination.
The burning of every single muscle is such a thrill... Just lying down is a reward in itself at that moment :).

Well, seeing as I can't afford to go to the gym atm, I usually just dance at my place (either w/ a video game or w/o one), do some cardio, go out running and walking, I do a lot of pilates and I just started with yoga (want to be more flexible), and some circuits from various websites.

Mountain climber, Plank, and knee to over crunches. These workout are every effective. It's can destroy belly fat and good for your abs. :) I currently doing it

I do random push-ups until I can't stand anymore, mostly because I'm bored all the time. The numbers are slowly rising.
