Stronger Materials - Our thigh toner is made of stronger ABS and fiberglass, and is equipped with anti fatigue metal springs inside, which makes it more durable. After more than 50000 high resistance bends, it can still work as it was in its initial state.More Considerate Design - Many high resistance kegel trainers have a disadvantage of easily squeezing their thighs during exercise, causing pain. We have thickened the thigh pads of this hip trainer and redesigned them to fit better according to the shape of the inner thigh, which can greatly alleviate thigh pain caused by high resistance exercise compression.More Training Methods - We have added many useful accessories and features. A resistance strap that can be used for warm-up and abduction exercises, a thigh strap that can secure the legs to prevent thigh trainer from slipping, a replaceable handle that can be used for upper limb exercises, and our matching skipping rope can be attached to the handle for aerobic exercise.Kegel Exercise - Regardless of gender, using our kegel trainer pro for Kegel exercises is beneficial for the body, which is very beneficial for lower limb training. Our Kegel Master has visual resistance and counters, which allow you to gradually exercise according to your own training plan. Studies have shown that progressive training can improve training effectiveness.Further Resistance - We further increase the resistance of the thigh master (up to 132 pounds), provide the most professional inner thigh training, and do effective exercises. Unlike other products, easy adduction exercises do not provide good exercise for the thigh muscles. Some inside thigh exercisers may find it difficult to increase resistance, but we have optimized this part so that even the maximum resistance can be easily adjusted with the knob.
