Sandbag Training can be a hell of a method to getting some of the kinks out of your training and teaching you how to stabilize the body with an object where the weight shifts. When it comes to Sandbells, it's a great way to utilize this in that regard. From Shouldering to Carrying to doing all sorts of stuff with these things.
Training the Legs with a Sandbell offers great resistance and added benefits to working the muscles to a greater capacity than with a typical barbell or dumbbell which could add some cool benefit to what you're already doing. 2 Exercises that I've worked on for a couple days now that hammered out the legs hard was doing the Squat To Stand and the Front Squat or a better name for it, the Bear Hug Squat. The STS is an exercise similar to lifting a stone where you get the Bell into position in a deep squat and once you have it in a good grip, stand up, drop it and repeat. Because of the shifting of the weight, it's not always easy to get a good grip every time. Here's a demo here to see what I mean....A few sets of these and you'll be feeling it.
The Bear Hug Squat is pretty damn simple, pick up the Bell, squeeze it against you and start going up and down. Unlike a barbell, dumbbell or kettlebell for that matter, you're working a bit more of the core in my opinion as you work on keeping the back steady and in control. You may lean a little bit and create more of that natural feel like picking up a box or a sack of flour. When you work these like a madman, you'll be jacking up some hefty hormones and building some incredible strength. Some guys work light or heavy depending on their goal. I've only got the 70 lb which in itself can be a bitch and others work as heavy as 200 lbs or more (strongmen mostly) but for the best weight in this manner, 100 lbs would be more than enough for many. Personally, I may go 150 if I work hard enough but that's the highest I'll go, maybe 170 if I'm ambitious but I don't need to go that heavy to get something cooking.
These two simple exercise will give you some insane strength and power. With a good clip, you can get some serious cardio out of it as well especially if you're an athlete training for a sport like Football, Wrestling or MMA. It's the classic moves of the Old Time Strongmen that gave rise to what is possible to have that ruggedness and mental toughness. Squats are no joke and Sandbells or Sangbags for that matter are just going to murder you with a vengeance. It builds real strength.
You know you busted your ass when you feel things you normally don't feel after a training session as you'll find out your fingers may be sore, your core is sore, your shoulders are on fire and your traps feel like they went to war. Not saying being sore is the greatest factor to determine a good workout, I' am saying that your muscles are being used in a way you're not used to because of how awkward the bag is. Go old school and you can't go wrong. Have an amazingly awesome day and I'm going to check out the Freestyle Wrestling that starts today at the Olympics....USA USA USA!!!
