Saturday I used only sandbags in my workout and burned 641 calories according to my HR monitor. In one exercise I used a slight assist from a TRX, but the workout took 45 minutes and worked every muscle in my body.

The TRX suspension trainers are supposed to be “all core all the time” because your core is activated to some degree in every exercise.  Same thing with sandbags – you’re always working your abs, low back and hips during an exercise.

Cardio strength training (interval training) is a great way to build lean muscle tissue and burn fat at the same time.  For example, my average heart rate for this workout was 78% of my max, with the peak HR reaching 98%  (pretty intense).

So a 45 minute workout at 78% will obviously burn some calories.  By doing more intense interval training you go into oxygen debt, where you are breathing heavily.  Research has shown that this can elevate your metabolism for 24 hours or more AFTER you have stopped exercising!

That’s one of the things I like about sandbags – improved fat burning efficiency while improving your coordination in different movement patterns.  The exercises train multiple muscles to work together at the same time.

I did step ups, overhead presses, high pulls, partial rotation deadlifts and an overhead rotational lift that is often done with a medicine ball.  I kept the rest periods between exercises minimal which keeps your heart rate up and stimulates your fat burning hormones.

One of the reasons you’re metabolism stays elevated after this workout is because of the fast twitch muscles that are worked with the exercises that focus on either strength or power.  More muscles used equals more calories burned but you also have the “afterburn” effect going on as these muscles are being repaired after the workout.

These workouts can take a lot out of you and need to be progressed gradually.  I have my baby boomer clients doing most of these same exercises and it allows them to get in a fast, efficient workout – letting them spend more time with family and friends.

I really could feel it in deep in my abs the next day, particularly from the overhead rotational lift with the sandbag.  I have taught those 15 minute ab workouts before at a healthclub and would never feel it in my abs like I do with the sandbags, or even the TRX.

Here is a video from coach Josh Henkin that shows a few examples of sandbag training.

Get moving!
