When you\u2019re laying on hard, uncomfortable floors, doing crunches and sit-ups, you\u2019re causing unnecessary strain on both your back and neck. The best ab machine to improve your core, without causing so much stress, is the Tristar Ab Coaster Max. It gets you off the ground and gives you the tools to continue doing core strength training in a much more comfortable way.\r\n\r\nWhy We Like It - Tristar Ab Coaster MAX Review\r\nReduce the strain on your back and neck with this advanced core strength exercise equipment. Forget ab rollers and sit ups, this machine takes your core strength training to the next level.\r\n\r\nPerformance\r\nForget ab rollers, sit ups, ab crunches\u2014the Tristar Ab Coaster Max removes those worries and heads in a different direction. Rather than strain your back and neck, the Tristar Ab Coaster Max swivels and moves as you do to strengthen abdominal muscles, rather than let your neck and back take on the pressure. The Ab Doer 360 was similar in nature, but still required you to do most of the work. Because it targeted more than just lower abs\u2014upper and mid too\u2014in such a focused way, the Tristar Ab Coaster Max is one of the best ab machines around.\r\nDesign\r\nSince this is an entire exercise machine, naturally it\u2019s bulky and heavy, with a dimension of 48.1 x 15.3 x 14.1 inches and weighing under 55 lbs. Fitness equipment like the Tristar Ab Coaster Max needs a fair amount of real estate to make use of so you wouldn\u2019t want something like this in your home if it\u2019s small. If you still want some kind of home gym, consider the Star Uno Ab Machine for an ab workout. It\u2019s smaller and supports up to 8 different core exercises.\r\nValue\r\nBecause the Tristar Coaster Max Fitness Ab Machine is so good at its job, we can easily recommend this to anyone needing serious core strength exercises. However, you should understand two things: it\u2019s strictly for core strength and it is not for beginners. It\u2019s certainly easy to understand, but this machine is best suited for someone who wants to take their core strength to the next level. If you\u2019re someone who wants to spend a few minutes a day working on their core, you\u2019re better off going with a CAP Barbell. It isn\u2019t worth spending $200 (free shipping) for a machine you only use for a handful of minutes a day.\r\nTristar Ab Coaster MAX Review Wrap Up\r\nAs far as core strength training is concerned, the Tristar Ab Coaster Max is the bee\u2019s knees. It targets more than just the center of your core, and done so without causing strain on your neck and back by getting you off the ground. It\u2019s bulky and takes up space, but only the least dedicated are concerned with those issues.
