Nutritional Support Before Strength Training in One Drink: GronG "All-in-One Pre-Workout"

Ultimate Life Co., Ltd. (Head Office: Higashinari-ku, Osaka, President: Yuki Tanaka), which sells supplements and fitness equipment, will launch "All-in-One Pre-Workout 250g," a supplement to be dissolved in water and consumed before training, under the "GronG" brand on July 11, 2026 (Sat) via Amazon and other online retailers. This product is packed with ingredients recommended for those who want to train with focus or achieve a training pump.

Development Triggered by Customer Feedback

The development of this product began based on feedback from members of our 24-hour gym, "GronG GYM 24." The trigger was a request from a member to "create a supplement to drink before strength training." To develop the product, we solicited opinions on the ingredients desired in a pre-workout through a survey targeting members of our online store, "GronG Official Shop," and others. We also conducted tasting sessions at "GronG GYM 24 Midoribashi Store" and incorporated customer feedback into the flavoring. After approximately 3 years, we completed an all-in-one pre-workout packed with the ingredients needed before strength training.

Product Features

1 Contains Arginine and Citrulline, Standard Amino Acids

Each serving (8g) contains 2,500mg of "Arginine" and 800mg of "Citrulline." Both arginine and citrulline are amino acids recommended for people seeking a training pump.

2 Beta-Alanine Supports Endurance

Each serving (8g) contains 1,500mg of "Beta-Alanine," an amino acid that supports that "one more push" during training. Beta-alanine has abundant scientific evidence and is recommended by the International Society of Sports Nutrition (※).

3 Mild Caffeine Content of 100mg

"Caffeine" is useful for shifting motivation, but depending on the timing and amount consumed, it can affect condition management at night. Therefore, to make it easier to use even for training in the evening or later, the caffeine content is set at a mild 100mg per serving (8g).

4 Abundant Support Ingredients

As a support ingredient, 240mg of "Citrapeak®," a citrus-derived ingredient also drawing attention in the sports nutrition field, is included per serving (8g). "Citrapeak®" is a highly soluble raw material containing the polyphenol "trans-hesperidin," recommended for those seeking enhanced training sensations.

Furthermore, 2,200mg of "Citric Acid," beneficial for maintaining performance, is included per serving (8g), along with 11 types of vitamins essential for body building.

※ "Citrapeak" is a registered trademark of Nagase Viita Co., Ltd.

5 Easy-to-Drink Lemon Flavor Before Exercise

This product is finished with a refreshing lemon flavor that is easy to drink before exercise. In tasting sessions conducted at our 24-hour gym during the development phase, all participants highly praised its taste (※).

※ Based on the number of respondents who answered "Delicious" or "Somewhat Delicious" in a tasting and questionnaire survey conducted from February 24, 2024, to March 1, 2024, targeting 34 members of GronG GYM 24 Midoribashi Store.
