Though canines love tennis for its bouncy yellow balls, humans appreciate the freedom to bark loudly with each swing and bury their favorite rackets all over the court. Become a tennis beast with today's deal: for $45, you get five weeks of group tennis classes, plus full club access for the duration of the classes, at Five Seasons Family Sports Club (a $97.50 value). The hour-long lessons take place on Saturdays at 11 a.m.; the five consecutive weeks begin after your first class.

This five-week course is a condensed version of Five Seasons' 10-week ACE Program. Students get all the perks of the program without the commitment. A certified tennis pro will impart the essentials of stroke technique, serving, and playing the game competitively. Participants get to put the tips and tricks to the test while practicing against understanding opponents that aren't comprised of pixels.

During the five weeks, tennis-pros-in-training can also enjoy full access to the rest of Five Seasons, which includes an indoor pool, indoor track, indoor basketball court, more than 100 cardio and strength machines, and studios to accommodate more than 50 group classes a week. Visitors to the facilities can luxuriate in saunas, whirlpools, and a casual dining area with a bar. Five Seasons provides all the amenities necessary to stay fit and entertained during Dayton's annual five seasons of winter.
