This is lovely @dobartim.

Riding helps our cardiovascular health a whole lot.

Regular cycling stimulates and improves your heart, lungs and circulation, reducing your risk of cardiovascular diseases.

Cycling strengthens your heart muscles, lowers resting pulse and reduces blood fat levels.

Cycling is an aerobic exercise, which is the kind of exercise you need to perform to lose fat on any part of your body. Aerobic exercise burns many calories, and the key to losing weight is burning more calories than you consume.

Because you ride with your legs, some muscles are toned and these muscles are :

1. Quadraceps muscles (front of thighs)
2. Hamstrings (rear of thigh)
3. Calf muscles.
4. Hip flexors.
5. Gluteus Maximus (your butt)
6. Plantarflexors of the foot.
7. Dorsiflexors of the foot.

So I am sure @dobartim and @tatjanastan are having a great burst of energy.
Keep riding
