If you have been curious about various fitness classes and opportunities but not sure you want to take the plunge, now is the time to experiment. Starting this Saturday, Chinn Aquatics & Fitness Center will be hosting a week of free events and classes.

From April 14 to 20, Chinn will be celebrating its 21^st anniversary by offering its best discounts of the year, free classes, free body composition analysis, free blood pressure screening, special free swim classes, and more.

Saturday, April 14, is the big sale day, with 20 percent off all six and 12-month passes (and a T-shirt with purchase), but all throughout the following week there will be discounts and coupons available for both passes and personal training packages.

The center will be holding its regular aerobic, strength and water classes, all of which are free to the public for this week. There will also be special demo classes free to the public on a first-come basis, including Gravity 101, Aqua Zumba, and TRX.

There will be demos, trainers, and other experts around all week to answer questions and help you figure out what might be the best fit for you.

Here are some of the week’s highlights:

• 20 percent off discount on 6/12 month passes on Saturday—10 percent off the rest of the week
