Run uphill to shave away your inner thighs.
The inner thighs can be a tricky and stubborn zone to tone, especially if you don't want to lie on your side performing countless repetitions of leg lifts. Instead, strategically perform a double duty cardio exercises that not only burns loads of calories, but also strengthens, sculpts and tones your inner thighs as well.
Make a Splash
Swimming is an excellent exercise for toning your inner thighs, according to an interview with swim champion Sharon Davies in the Daily Mail online. Exercising in the water is also gentle on your joints, making it an effective cardio choice for anyone with arthritis, obesity or weight issues, injuries or the elderly. Freestyle and the backstroke both tone the inner thighs, but if you want to raise the stakes, try performing the breaststroke instead. As you circle your legs out and back in again, you'll activate your inner thigh muscles against the resistance of the water. For a full cardio workout, swim at a moderate to vigorous pace for 20 to 30 minutes.
Sprint Like a Champ
Running in general is an excellent inner thigh toner, but to really feel the burn in your thighs sprint uphill as fast as you can. Hill sprints force your thighs to work harder as they propel you uphill, working against the downward push of gravity. Be creative with your exercise, finding a hilly park in your neighborhood or using the incline feature of the treadmill at the gym. The key is to sprint in intervals, mixing 30-second to two-minute bursts of sprinting with longer periods of rest or jogging at a moderate to slow pace.
Exploding Box Jumps
Plyometric exercises are a combination of cardio and intensive strength training that encourages explosive power, speed and agility. Lower body plyometric exercises -- like box jumps -- tone the inner and outer thighs and buttocks. To perform a box jump, you'll need something steady and secure to jump on, like a low bench or flat stool. Stand directly in front of the box, bench or stool, bend your knees and jump as high as you can, landing with both feet on the top of the box. Immediately jump to the other side of the box, turn around and jump back onto the box again. Continue jumping on and off the box as fast as you can for two minutes and then pause and rest for 30 seconds. Cycle though five to 10 rounds of box jumping to complete your workout.
Just Take the Stairs
When it's cold outside and you need to squeeze in a thigh-toning exercise, take to the stairs in your house or office building. Running or walking up and down the stairs tones your entire legs, including the inner thighs. The faster you run up the stairs, the more you get your heart and lungs pumping, burning more calories in the process. For a thigh-blasting workout, put on your running shoes and run up and down the stairs for at least 20 minutes. Pause and rest whenever you feel like you are out of breath and need a break.
