First of all, please be safe out there on New Years Eve. Please take care of each other and don't let your friends or family drive impaired. Allow them to stay at your place or get them a cab. There are many different agencies that will pick you or them up for free on this occasion, please use them. Sadly, there will be a lot of what I call "amateurs" out there driving tipsy so try not to add to the issue.
Call on people who might be alone and show them you care. Get out and take a nice brisk walk. Get some fresh air.
I always take New Years Day off from work. I've done that for decades now because I try to start the year on a calm, easy note. Maybe the rest of the year will follow suit. Thats what I tell myself at least. I try!
If you make a New Years resolution to get fit, start with baby steps. Don't go full tilt into a boot camp class if you haven't done anything in years. You'll never make it to the end of the week, let alone the end of the year.
Find something you like to do. It'll feel less like a chore and more like a fun time to pursue. A dance class, water aerobics, boot camp (if thats your thing), running, barre class, weight lifting, walking, whatever you can fit into your daily life. Try to do it around the same time of day to make it a normal part of your day.
Remember, cardio-vascular (aerobics) work doesn't need to be done all at once. It can be done in 3 bouts of 10 minutes, 2 bouts of 15 minutes, etc. but should be done for a minimum of 30 minutes/day and you should feel it. By that I mean you should know you're working, not dying, but working. Not being able to breathe solely out of your nostrils is 1 way to know you're achieving a workout.
Strength training, don't work the same muscle groups day after day but you can strength train every day. Just split your body into parts ie; upper body 1 day, lower body the next or chest, back and shoulders 1 day, abs, biceps and triceps day 2, and hips & legs day 3 and lather, rinse, repeat.
Change your workout up. Swim 1 day, strength train the next and dance the day after that, just for example. Cross training is great.
Hook up with a trainer for solo workouts to give you incentive and technique to achieve your specific goals, take classes, get a workout partner to keep up motivation, get a dog to walk! something. I promise you, after the initial issues associated with starting a fitness regimen, the post exercise soreness and all, you'll begin to see results, feel better, look better and be happier.
In any case, go out and treat yourself to a wonderful New Year filled with health and happiness. It begins with you.
Peace out and keep dancing.
