The big question in every non runners mind is how do I get started running? I'm going to try and simplify it for you and give you pointers to get started and to keep going.
It's actually quite simple in the fact that all it really takes is you slipping on sneakers and some workout clothes and getting out your door but let me stop there and let's dig a bit deeper. The first thing you really should do is go to a running store and get fitted with the right sneaker for you and yes most the time they are not the cutest, prettiest, most stylish sneakers but your feet will thank you, also make sure to go up a half to whole size bigger because your feet swell when you run.
Now that you are fitted and your feet are happy go out for a 20 minute run keeping a nice comfortable pace - do a talk test, if you can comfortably hold a conversation then you are running at the correct pace. Don't run like you have somewhere to go because you will get home winded and say I'm never doing that again! In the beginning it's important to focus on time and not distance. You should run three times a week for 20 minutes until this starts to feel too easy and then up your time to 30 minutes and so on.
You do not need a fancy watch but it is helpful to have some type of watch that tracks time, distance and pace. There are many apps as well out there that can be helpful in the meantime. A favorite free app that I feel is accurate is Strava. I would suggest if running with your phone to invest in either an arm band or my favorite the SPIbelt and it allows you to carry your phone, keys and some cash and it doesn't bounce around.
Make sure that you are cross training on the days you are not running. Cross training is anything other than running but my suggestion is one of the days do core work, squats/lunges and weights. It's important to build an overall strength on non running days because just running does not build all the muscles needed to be a strong healthy runner.
Lastly stay flexible - this will help with injury prevention. It's important to do a short dynamic warm up, start your run slow and do static stretching at the end of your run when your muscles are warmed up. Another wonderful thing is foam rolling, it's one of those things that "hurts so good", you can find how to videos on youtube to follow along with.
Find a friend to run with, join a group - Aktiv Mom's Running Community will be kicking off in January. It's important to establish accountability and to make it fun!
