Home workout success??

I have been working out at home for the past 4 years and would not go to the gym. Some things to consider that I have found really helped me.
1) Find a consistent time.
I found morning worked best as I could always dedicate that time to working out. Where-as evening would always tend to get co-opted by kids activities, wife, work, etc, etc.
2) Find a good (preferably dedicated) space.
When I first started out I was using my bedroom with a bench and powerblock dumbells. They made a fair bit of noise so I would tend to stop early as my wife would get annoyed. Then I moved to the den but again needed to be quiet to avoid waking the kids and would have to pack everything away after each use. Then to the garage which worked pretty well but was cold and added a layer of challenge to starting in the morning. I have since set up in the basement (since kicking our tenants out) and have a dedicated space always set up which is awesome. Compliance is way up since I found that.
3) Make a plan and have some options.
I started out just working out on my own using a 4 day split. Inevitable if I was going to skip a day it would be legs (which I still hate). I then did P90X but it was a serious time commitment which made it unsustainable past the 90 days for me. I moved on to Kettlebells using the AOS-Providence DVD which was great for me, full body workout and only 45min per workout. which I did 3x per week for about a year. Then moved to do more Yoga with a Rodney Yee video, harder kettlebells with AOS-Newport, and self created weight workout with the app "fitnotes". I find I need to switch things up every 3-4 months or I get a bit bored and lose motivation. I now have a good selection of DVD workouts and try to slot in 1-kettlebell, 1-flexibility/yoga, and 1-weight focus a week and then have a floater that is a choice. I like the DVDs because they always seem to push me harder than I would push myself. I hate Tony Horton's stupid jokes so watch with the sound off when I do any P90X videos.
4) Get some instruction
Form is critical to working out. I hurt myself when starting out with kettlebells and got training from both my kinesiologist, Physio and from an certified instructor. No more issues.
5) Log your workouts.
Just like logging your weight loss, logging how you are improving (higher weights, less rest, more reps, etc) is good to highlight progress and keep you motivated. Remember fitness goals are different from weight loss. Measure your resting heart rate, your recovery time and endurance. These tend to be where you see gains from working out. Weight loss is done in the kitchen, the scale is no measure of fitness.
6) Set aside some money each month for new equipment.
A home gym is cheaper in the long run but dumbells, kettlebells, mats, DVDs, Barbells, benches, racks, etc, etc all cost money which can seem more expensive in the short term. Personally I set aside $20/month. Started with the powerblocks, then added a bench and mat, then P90X DVDs, then a single kettlebell, then 3 more kettlebells , Have my eye on a squat rack and Olympic bars and weights now. Probably have about $2000 worth of equipment now but lots of these are birthday and Christmas gifts.

Keep it up, after a few months you will feel awful when you don't workout.
