Fat Face Activ88 crop top / Fat Face has a great activewear range and this crop top comes in many different colours. I have the black version. It is very useful to wear under sports vests and is extremely comfy.
Nike Lunarglide 6 / I have recently bought myself these trainers and I love them! They are bright and vibrant so stand out when wearing darker clothing. They have lots of support for the ankle which provides stability when running and cushion your feet from the Lunarlon foam on the lateral side.
Nike elastika 2.0 / This tank top is great for those sweaty gym sessions as it is made from sweat-wicking fabric and has a comfortable fit, which will allow free movements.
Baby-G white BG1005M-7 / I have a similar G-shock watch to this one, it is very durable which is perfect for surfing and playing other sports. A watch with a stopwatch will help you keep track of timings of rest when carrying out sets, as well as helping with other training such as intervals.
Roxy virtigo hoodie / This is similar to a Roxy hoodie I own and is perfect for something to throw on before or after a gym session.
Black frill trim cable knit socks / These socks are from New Look and although they are not specific sport socks, I would still wear them to the gym because they bring a quirky touch to a gym outfit.
Nike sport water bottle / It doesn't really matter what type of water bottle you take to the gym. I own this one, its leakproof valve makes it hassle-free when running and performing other sports.
Apple headphones / When training at the gym I always listen to music, so headphones are crucial. I picked this pair made by Apple, which hooks over the ears for a more stable fit.
