If your workout time is limited but you want to burn a lot of calories and get an effective treadmill workout, here are four quick and fun treadmill workouts for you to try:

1. 30-Second Sprint Intervals

This workout makes time fly by and leaves you drenched in sweat. If you've never done speed training before, make sure to follow these rules:

• Warm-up: Start with a 1-minute easy walk. Continue with a 5-minute light jog. You should be able to carry on a conversation. This will get your blood flowing and muscles warmed up.
• Sprint Intervals: Increase your pace (heavy breathing) for 30 seconds. Jog lightly for 90 seconds to recover.
• Repeat: Alternate sprint and recovery intervals 9 times (totaling 18 minutes).
• Cool Down: End with a 4-minute easy jog or brisk walk to cool down.

Total Time: 30 minutes

2. Side Step Workout

This workout combines running and walking with some great side shuffles that really work your hips and quads.

• Warm-up: Start with a 1-minute easy walk. Continue with a 4-minute light jog.
• Side Shuffles: Slow down to a walking pace, then while holding the side rails, turn your body to one side, squat slightly, and begin side-stepping. Keep it simple – one foot shouldn't cross over the other. Continue for 30 seconds, then return to forward walking.
• Running and Walking Intervals: Speed up to a conversational pace for 2 minutes. Slow down to walking pace and side-step for 30 seconds on the other side.
• Alternate: Continue alternating 2 minutes of easy running and 30 seconds of side-stepping until you reach 20 minutes.
• Cool Down: Finish with a 5-minute easy jog or brisk walk.

Total Time: 30 minutes
