We all know Madonna takes her fitness routine incredibly seriously, as she shows the results constantly on stage and in print. Owning her own gym near her London home must help a lot – it certainly gets daily visits from her when she's in town! We've seen Gwyneth Paltrow using Madonna's fitness facilities before, and she visited again this week. Gwyneth is pictured with Madonna's trainer Tracy Anderson who is helping to keep her amazing figure in tip-top shape, so that when she wears the heels she's become associated with she has the strength to stay standing!

Later in the day a new member popped along to have a workout – Stella McCartney (love her jeans). Working out with friends definitely helps keep your motivation up, so it's great to see these women encouraging each others' fitness! AIf you're inspired by them pop over to my pal FitSugar for heaps of amazing tips and features.
