The Bowflex SelectTech 552 is a great set of dumbbells for P90X users or anyone who wants to be able to work out in their own home without taking too much space with lots of dumbbells. It features weights up to 52.5 pounds per dumbbell for a total of 105 pounds, an ergonomic design, an instructional DVD, and metal locking tabs. It also has a very quick adjustment time and 2.5 weight intervals for responsible strength training.
Weights from 5 to 52.5 pounds
The Bowflex SelectTech 552 series adjusts from 5 to up to 52.5 pounds; this will be more than sufficient for most users, including P90X users.
Instructional DVD included
The Bowflex SelectTech 552 series includes instructional workout DVDs specifically geared towards these dumbbells, as well as an instructional video on how to use these adjustable dumbbells.
Metal tabs for locking
The Bowflex SelectTech 552 series includes metal tabs for locking between adjustments; this is an improvement over plastic tabs which can break and damage the equipment or cause injury to the user.
This model is one of the more ergonomically designed adjustable dumbbells available on today’s market. It is designed to fit easily within your hand; the bar is thicker than typical dumbbells, but it is grooved and shaped to make for easy handling no matter what weight you set it at. The plastic coating means that you are less likely to develop callouses than with metal units.
Small weight increments
The weight increments increase by 2.5 pounds up to the 25 pound mark, which is better than adjustable dumbbells that leap up in five or ten pound increments. Going from 10 pounds to 12.5 pounds is far preferable than going from 10 pounds straight to 15 or 20 pounds. After 25 pounds, the Bowflex SelectTech 552 increased by 5 pounds.
Quick weight change time
Especially useful for P90X users who have limited time between exercises to adjust their weights, the Bowflex SelectTech 552 series takes about 5-10 seconds to adjust to higher or lower weights, putting you well within the 15-20 second time period allowed in P90X. Non-P90X users will also appreciate the speedy adjustment time.
At 16 inches long, these dumbbells may be cumbersome for some users. The efficacy of most exercises is not influenced by dumbbell length; however, users buying these dumbbells specifically for P90X exercises should be aware that the longer length does affect the general comfort of some P90X-specific exercises. It does not necessarily mean you cannot do them, simply that it will be more cumbersome than using your typical, shorter dumbbell.
The Bowflex SelectTech 552 series is one of the top-performing adjustable dumbbell sets on the market today. Its durable design and quality manufacturing means it will last for a long time in your home, and the speedy adjustment time and ergonomic design will be a benefit for everyone from the casual to serious weightlifter. P90X users should seriously consider this model for their home gym.
