Training supplements are often a shock to our financial possibilities. But science sometimes steps in with a solution both practical and budget friendly.

An amino acid found in watermelon has the potential to boost the amount of weight you can grip and add more reps to your workout. Citrulline malate, as the acid is called, buffers muscle fatigue if you consume it daily. You may want to blend a pre-workout smoothie with half of one. But taking one in your gym is not really the better solution:)
