so ive been hearing a lot that if you start off walking for say 5 minutes, and then you start to run for 1-3 minutes and then repeat until you reach your goal destination, itll be just as efficient as it would be if you just ran the whole distance. my doctor said as long as i keep my heart rate the same speed then it it beneficial. has anyone done this method??

Walk 3 mins

Jog 2 mins

Run 1 min

....repeat 3 times... total 18 mins= wrkout done!

I am still a work in progress and I would not consider my "faster jog" really running BUT I have lost 48 lbs since July 16th.

About 3 weeks ago I increased my workouts to 1 hr walks w/ occas slow jogs (just b/c I am trying to increase my over all endurance b/c we have a trip planned to tour the Vatican next year), but I am seriously thinking of going back to this 3 x wk.

--good luck

You can try the Couch to 5k. It is also available as a mobile app. Many people here have used it with success. I have used myself in the past and liked the program. You can repeat weeks if you find it too difficult.
