It seems that for any exercise regimen to 'take,' our outlook needs a hearty shift. We have to begin viewing happiness as a long-term prospect, and not something desperately needed right this second. No easy feat, but here's the good news: there's zero heavy lifting involved in adjusting our attitudes. So hey, that's something, right?
If you are barely breaking a sweat anymore and feel like you are simply going through the motions with your routine -- kick it up a notch! Playing with the inclines and speed will take your mind off of counting down the minutes that pass. It will also make the workout more of a challenge, meaning more calories burned even faster!
