Hi Boris. 2.5 kg increase works well on all the lifts in the beginning. But first on the press, and afterwards the bench, you will need lower increments, like 1 kg. So get your hands on 0.5 kg micro plates. Increasing less than 1 kg on the upper body lifts and 2.5 kg on the lower body lifts is a waste of time for a 26 year old male, and at that time, it is better to change programming to weekly increases. Hope this gave you some help on the weight increases.
