Right now I ride without clipless pedals. I dont know the exact terminology of the thigh-muscles group, so I'll refer to them as front thigh muscles and back-thigh muscles.
I feel like the front-thigh muscles are getting stronger than the back-thigh muscles. Is this normal?
If I get clipless pedals (and use them correctly) will it start improving my back-thigh muscles as well or do I need to do additional gym training (like when you lay on your front, have weights attatched to your feet, then you curl you feet back above your back-thighs, thus developing the back-thigh muscles) ?
