Yes. Appropriately designed and supervised strength training can be suitable for teenage girls. The starting point is coached movement skill and submaximal effort, not a maximum lift.
Done well, strength training can give a teenage girl more than stronger muscles. It teaches her how to practise a skill, understand effort and see progress as something she can build, not something her body either has or lacks.
Start with coaching, not a maximum lift
A teenager does not need to prove her strength on day one. The first job is to learn the major movement patterns and find an exercise variation she can repeat with control.
At Evolved, PRIME guides that decision: Posture, Range, Identify, Measure, Evaluate and Evolve. If a squat loses position or comfort, we may reduce the range, add support or use an easier variation.
The next exercise is earned through repeatable movement, not age or ego.
Use effort without training to failure
A set around RPE 7 means it was challenging but several good repetitions remained. That gives a newer lifter room to learn.
Load is only one measure; range, repetitions and consistency matter too.
Research in female youth supports appropriately designed resistance training for strength development. The useful distinction is not weights versus no weights.
It is supervised, progressive training versus unstructured imitation.
Let training become a long-term skill
Before a main lift, Evolved progressively introduces the planned load through 20% × 12, 60% × 6 and one acclimation repetition at the intended working weight. That gives the coach several opportunities to observe movement before demanding sets begin.
Our programme runs in 13-week blocks, with load generally rising as repetitions fall before a reduced-load and testing week. A teenager should not be rushed into the adult end of that loading range; the structure is a way to develop skill and capacity over time.
The best first result is not a number on the bar. It is knowing how to enter a session, perform the work and understand what happens next.
Continue with Nutrition and Fuelling
Strength training creates the demand to adapt, but a teenage girl also needs enough food for growth, school and sport. Read what a teenage girl should eat to support strength training, school and sport, including the warning signs a coach, teenager and parent should communicate and refer on.

Youth training should be age-appropriate and supervised. Pain, injury, medical conditions and eating or body-image concerns may require qualified individual care.
