It would be a good thing to go check in with your doctor. Most importantly, if you feel uncomfortable or dizzy you need to look after yourself in class and not worry about 'hurting the teachers feelings', stop what you are doing and check yourself... ie put yourself in a comfortable position and breathe regularly, your teacher is also there to assist you, if you are in trouble let them know!
If you are experiencing postural hypertension, it is a common condition and its important to understand what is going on with your body while exercising. If this is the case you should get a clearance from your doctor. If this was an isolated case and you have not experienced it again it could have been an episode induced from stress, hormonal or other blood pressure/blood sugar issues. If you are taking BodyBalance after BodyPump you need to understand that is a long periods of exercise and your blood sugar levels and levels of fatigue are stressed. BodyBalance is an engaging, strengthening and intense class and yes, while also relaxing and meditative it is not by any means 'easy'.
It is super important that you breathe rythmically and evenly while you exercise, never 'hold your breath'. This is something that is particularly important in a yoga based program. There is synchronization of your breath and the movements in BodyBalance....( a vinyasa is the foundation of the sun salutation). The movements are linked to connect the poses and the cues your teacher should give you for the steps to take to get in and out of the poses. Your movements should coincide with either an inhalation or exhalation. The speed of the movements also means that our breath moves faster. Many beginner participants may gasp or hold breath or breathe too rapidly which can cause dizziness. Its all about muscular and respiratory capacity.
Please take care of yourself, while I personally teach BodyBalance directly after teaching BodyPump or BodyCombat regularly... I need to ensure that I am well hydrated and energized to teach to my full potential. There are some great glucose gels or light energy bars you can nibble in between class to help you through the two hours. What you are experiencing could be fatigue from the back to back. There is good info on this website about exercise and nutrition.. Check out the 'healthy lifestyles' section.
Cheers.
