Some suggestions include:

• Keeping a grade of at least 1% on the treadmill
• Keep your revolutions per minute (RPM) at least 90 on the stationary bicycle
• Try a new machine at the gym

Also, now that the weather is warming up, try taking your workout outdoors.  Head over to a local track and try running a flight of stairs between laps.  Make sure your bike is in working order for those impromptu bike rides with your family. Grab a racket and begin tennis, again. All of these changes can help with motivation, fitness level and enjoyment. ​
