I write this having received an email from a client who's having a hard time being consistent with his AM Boot Camp training.
I'll admit that it's not easy waking up 2-3 times a week, early in the morning when it's cold and dark. It's way easier to stay snuggled in bed.
As I get older, I believe more and more that genetics play a big part on whether or not we can stick to an exercise habit or not. Having said this though, I do believe that if you want excellent health and to reduce body fat, the effort has to be made whether you like it or not. You just have to do it.
If you know that the time of day just isn't working with your schedule, I suggest finding something that you could do from home, or while traveling. The best tools I'd use are a kettlebell or two (one heavy, one light), a jump rope, a Power Wheel, and a TRX like suspension trainer.
With those handful of items you could train where and when you wanted. Fitting it in when you are fresh.
Getting results and keeping the weight off comes from doing the basics. Eating protein, vegetables, and a little bit of fruit and healthy fats. With your training/activity it's a matter of pushing and challenging yourself. It doesn't have to be anything extreme, it just needs to be a challenge.
Just like I wrote to my client, I share this as it's my utmost wish that you get to a weight/place that you are happy with... be it training with me, or on your own.
