The article describes the studies aimed at examining the possibility to reduce the calendar time taken to get in top athletic form. After the first series of the experiments, it was found that the division of a training sessions into four smaller blocks allows to reduce by half the time taken to get into good athletic form, while the division of a session into six blocks was shown to reduce it by three times. In the second series of the experiments (on the material of the hammer throw), it was found that the use of a lightweight projectile (6 kg) on Monday, Wednesday, and Friday along with the use of a competitive hammer (7,260 kg) on Tuesday, Thursday, and Saturday does not reduce the calendar time taken to get in good athletic shape. In the case of the use of lightweight hammer (6 kg) in the morning training sessions along with the use competitive hammer (7,260 kg) in the evening training sessions, it was recorded the impact of the second training session on the first one regarding the reduction of the calendar time taken to get in athletic shape by half in throwing only lightweight hammer. When a hammer weighing 6 kg was used and specific strength training complexes were performed in morning training sessions, and a hammer weighing 7,260 kg only was used in the evening sessions, a two-fold reduction was observed in the calendar times taken to get in athletic shape in throwing only lightweight hammer.
