I would say keeping the resistance training “General” in nature, as you would with a sprinter. The fact that she comes to training and improves every week tells me that the demands of her gymnastics workouts stress her in a way that doesn’t require me to do more than 1 session per week.
I do lots of unloading sessions, as her coaches did not unload as much as I would have liked (so, the strength coach has to unload more to make up for it).
The jumps we do are only concentric (up onto a box). No landings, as I am aware of her requirements for landings and dismounts throughout the week. In most cases, we perform cleans, snatches, jerks or med ball throws and they satisfy our explosive movement requirements. Jumps are typically secondary options.
Our needs for strength training shift throughout the year. Sometimes preparatory strength, sometimes CNS loading. Sometimes basic postural reinforcement.
