While Tai Chi is based on Chinese martial arts we use it for health and relaxation. As a stylised, dance-like, form it combines balance, breathing and relaxation. It can be performed at your own level and shouldn't place extra stress on your body.
Practical Tips Don't force the exercises. Everyone has different limits and you're the only one who knows yours. Modify the way you perform the exercise or stop and rest before you reach your limits. For example, many of the exercises can be done while sitting or you can use a chair or other balance support. Relax and flow with the exercises, avoiding sudden movements or over-extending yourself. Coordinate your breathing with the movements. Know your balance limits and keep your movements within the limits. Focus your thoughts inward on your form, posture and breathing, rather than being distracted by what other people are doing.
