However, there are some ways to tackle the inevitable issues that come from getting that dream bikini body and feeling strong and healthy.
Chlorine damage from swimming protection cream
Philip Kingsley's Swimcap is an essential for any avid simmers.
The chlorine in pools can ravage your hair, and if particularly worrying for blondes.
Apply this before and after you hit the pool for instant protection.
Sun, swim and sports cleansing shampoo
We named this shampoo as a #HandbagHero after using it on holiday, but it's also designed for sports use.
The organic formula works to protect from sun, sea, pool and pollution, perfect if you work out outside.
It also just gives a great, fresh clean.

Dry shampoo for greasy roots
Washing your hair everyday isn't good, we all know this, the hairdressers have told us this.
So, what do you do when your sweat buckets in the gym? Trusty dry shampoo of course.
This one is our favourite for freshness, smell and lack of horrible chalky roots.
Hair oil for dry ends
Sometimes the feeling of sweaty roots is too much to just attack with dry shampoo.
You'll be amazed how much better it feels after a simple rinse.
This can dry out the ends of your hair, so use an oil, like this French wonder product - just make sure you avoid the top half of your hair!
