User questions & answers

Question:	Is there a lot of jumping required? I’m recovering from a foot fracture and can’t jump at all. Thank you
Answer:	The videos have 4 different girls doing the same workout just at different levels so you can pick which every level fits you. I like it a lot!
Question:	does the dvd comes in spanish also
Answer:	Whatever you need for your ability. You can also use resistance bands. I personally have hand weights/Dumbbells from 3-15lbs that I use. For the most part I use the 8 and 10 lb weights the most but it does depend on the muscle group.
Question:	I am looking for something that will help me lose as well as tone, would this set work? Has anyone seen results from it
Answer:	Hi Jenny. Stephanie from X-TrainFit here. The only equipment needed is dumbbells and/or resistance bands. Yoga mat is recommended but not required. There are some stability ball options shown, but one is not required. I hope this helps.
Question:	This is for woman’s or for man too
Answer:	I just finished the first week and not much jumping at all. For the very few parts that do include a jump type movement there is a person doing the modified version. I did insanity and it killed my knees, this wasn't hard on them at all. It is actually very low impact. A little too low for me. I think I need something between this and insanity. Thus wasn't enough to feel like a good workout for me, but insanity was too much.

Product description

Outside Bit Diameter: 5" Overall Length: 17" Approximate Inside Barrel Depth: 14.5" Approximate Thread Type: Industry Standard 1 1/4" (Directly fits our BLUEROCK Z-1 Core Drills) Note to buyers: Concrete coring bits are considered a consumable part. Bit life varies based on many factors including; material type, material density, depth of cut, hole diameter, drilling speed, wet/dry drilling and operator experience. As such, it is extremely difficult for BLUE ROCK Tools to assess individual projects and speak to how long a bit will last before it needs to be replaced. We consider these core bits to be mid-grade in their performance but sold at a low-grade price point. Our customers tend to consider these bits to be a better value compared to high-grade bits that are a lot more expensive. We often hear that even though high-grade bits may last twice as long, they cost four times the price and they are happy buying our bits and getting the same amount of feet cut for half the price. Wet type concrete coring bits are NOT designed to cut all types of rock. They are primarily designed to cut concrete. Certain types of rock can be cut, but it will limit the bit life. The decision to use these bits on materials that they are not primarily designed for will be done at the risk of the user and not covered under our standard business policy.

User questions & answers

Question:	I want to know if this can run through cinder block and if this is able to fit an sds plus adapter for the rotarty hammer drill please
Answer:	Uh. It's an auger, not a drill bit. I'm putting holes in oak trees for threaded rods with a big variable speed electric drill, low and slow. If the flutes catch and stick, like near the end of a deep hole, the drill itself will turn rapidly and bust your thumbs or wrist. So, low speed and patience. Also, most augers have a little screw to lead. It can only bite and pull in at a slow speed. I like to reverse the auger occasionally to clear out any big chips too. Hope this helps, Bob

Question:	Is this 3" id or od
Answer:	3 in OD
Question:	I need to drill a hole through brick to accommodate a 4 inch vent pipe. Will the 4 inch bit do the job, or do I need something slightly larger
Answer:	We drilled through a 8 inch cinder block wall with this bit. We also needed a 4 inch vent pipe...in our case for a dryer. It was difficult to get a standard 4 inch vent through the hole we bored. To have it work we inserted a sleeve through the wall made from sheet metal that was probably a little smaller than 4 inches and attached a 4 inch vent pipe on the inside and an outdoor vent on the other. This solution was easy and worked out great.
