Many people like working out without machinery. They like getting back to the basics. I like to call this type of workout Organic. The benefits of organic workouts is they are always reliable, and portable. You don't have to have any machinery to pack around, because working out organically needs no tools. Just you, your breathing, your muscles.
Jogging in the Sand- Of course any type of jogging, walking, or running can be beneficial to your heart, and muscle health. But if you can find a way to do this in the sand, nature will work you harder than regular pavement would if you were to go the same distance. If you don't have sand available, jogging uphill is a great alternative!
Sit ups, crunches & reverse crunches- Yea, the ab lounge is pretty awesome. But I'm sure we all remember how to do our sit ups and crunches too. Many people (especially us women) try to avoid them at all cost. In actuality, these are the fitness exercises we can use when away from the gym, or only have a few minutes a day to work on them!
Reverse crunches and jack knives are great too. In these exercises you lay flat on the floor and lift your legs together straight up in the air then straight back down (but not all the way down! let your ankles hover a few inches above the floor!). In a jackknife, the legs do the same thing, but when they go straight up, you pull front up as well, in a crunch + reverse crunch manor.
Lunges & Squats- These are great exercises that also barely get utilized. The best part is whenever you are alone you can drop a few squats, or lunge across the room and back. Do them while doing laundry, or cleaning the house, or hover over your chair for a few seconds before you sit down at work! Take advantage of your body's natural weight resistance. A great benefit to practicing these daily will come out on the dance floor. Sometimes tall girls (like me) have a hard time "pop lock and dropping it" or "getting low." But doing squats more often will help you get low and feel more confident about it!
Pull ups and Push ups- Now time for the arms! Don't forget do do a few simple push ups daily for arm workouts. Try and do push ups until you fail. ( a fail is a pause of three seconds or more between repetitions). As for pull ups, if you can't even do one, go back to what you did in high school. Jump up there and hold the pull up pose for as long as you want. Try these on a thick tree branch or other overhead bars you come across!
Have a happy workout!
