I would tell her it is not to late to improve muscle heath. Although I would advise her make sure her joints are in good shape to perform this. If she has previously been working out there should be no problem. If she has not been physically active in a while I would advise her to get her joint strength strong before she starts weights. After this I would advise her to start with light weights and body weight exercises such as a simple push up.
i hope this helps!
A concussion, as found on Google, is a "temporary unconsciousness caused by a blow to the head.", which means a really hard hit to the head, and then a knock out or a blackout
Some symptoms that are usually associated with a concussion can be but are not limited to: headaches, memory loss (if severe), nausea, vomiting, slurred speech, confusion, and fatigue. There can also be sleep disturbances, sensitivity to any type of change, such as air or light, and disorders of the 5 senses (sound, sight, touch, smell, and taste).
Push ups, because it's likely that you'd do push ups in gym. You must have balance to do them.
