Bodies, like frozen yogurt, can be difficult to keep firm during the summer. Tone your torso and still make it to the barbecue on time with today’s Groupon: for $149, you get a Slim and Trim spa treatment at Harmony Beauty Spa (a $350 value). This Groupon is valid at all three locations in Pinole, Vallejo, and Oakland.

Expert aestheticians at Harmony Beauty Spa tend to every corporeal corner and crease with treatments designed to streamline silhouettes in about 90 minutes. An Endermologie machine lifts tissues to tighten dimpled areas and increase collagen production, and ultrasonic waves work to boost metabolism. After the cellular reboot, micro-currents step in to stimulate muscle contractions and simulate exercise, firming areas less commonly exercised such as the abdominal elbow. Toned and trim physiques slip into sauna-like body wraps to further smooth contours and draw out toxins, emerging from their cocoons to reveal sleek abdominals and slimmer dorsal wings. A skin-refining scrub exfoliates expired cells and leaves surfaces as soft and luminous as a bonfire of loofahs. Harmony Beauty Spa also provides access to a shower and shower supplies for post-treatment cleansing.
