First of all, thank you for sharing this so honestly — what you’re experiencing is very normal, and you’re definitely not “out of shape.”
Let me gently clear the confusion.
About the numbers you see online……
There is no single “correct” number of Sun Salutations for everyone. Practices like 108 rounds are ritualistic and advanced, usually done on special occasions by seasoned practitioners. They are not a starting point and not a daily benchmark.
Is 5 rounds enough?
Absolutely yes. For a beginner, 3–6 slow, mindful rounds done with good breathing and alignment are far more beneficial than forcing higher numbers. Shaking arms simply mean your muscles are waking up and learning to support your body weight — that’s progress, not failure.
How many should a beginner do?
Start with 4–6 rounds at a comfortable pace
Focus on breath, form, and smooth transitions
Rest whenever you need — pausing is part of the practice
Should you increase every day?
No need to rush. Stay with the same number for 1–2 weeks, and only increase when your body feels ready. Even adding one extra round is enough progression.
Will you still get benefits with fewer rounds?
Yes — you’ll build strength, flexibility, circulation, and mental clarity even with a small number, as long as you’re consistent and attentive. Yoga is not about exhaustion; it’s about intelligent effort.
A gentle suggestion….
Some days your body may want fewer rounds, and that’s okay. Yoga is about listening, not pushing.
You’re doing beautifully by simply showing up each morning. Consistency and kindness toward your body matter far more than numbers.
