I’ve written about the best time to train in the past, but here are some additional viewpoints from Russian and Eastern European authorities on the topic:

• After sleep, strength is 20–30% lower and will gradually increase, achieving maximum levels after 3–5 hours upon awakening. (Source: Vorobyev, A.N. (1978). A Textbook on Weightlifting. (W.J. Brice, Trans.). Budapest: International Weightlifting Federation, pg. 167.)
• Plekhov (1988) recommends training during the active part of the day. Work capacity is elevated during two periods: 11 a.m. to 1 p.m. and 6 p.m. to 8 p.m. These are considered optimal times to work out. (Source: How to Structure Training (Chapter 4) from Vozmi V Sputniki Silu (Moscow, 1988). Soviet Sports Review, 26(2), June 1991, 66-69.)
• In Science of Sports Training, Thomas Kurz (1991, pg. 60) states: “According to chronobiological research conducted by Charles Winget, Charles DeRoshia, and Daniel Holley, the best time to conduct a strength workout is between 14:00 and 20:30 hours because hand grip strength is greater then.” Kurz also notes that strength performance tends to be better in the evening, and physical effort is perceived as easier in the late afternoon and early evening.

As you can see, there’s conflicting advice—some experts say morning, some say afternoon, and some say evening. The bottom line? Find what works best for you and your schedule, and train then.est to train in the morning, some say afternoon, and some say evening. The bottom line is to find what works best for you and your schedule, and train then.
