There comes a point, when you realise that lifting heavy weights, with horrific posture and poor technique, just isn’t a sustainable way to keep fit.
Here are some tips on keeping fit, as you approach your mid 30s:
1. Warm up like a mofo
Can’t emphasise this enough, one injury when your 35, and you might never recover. Wear plenty of layers and get a sweat on before you do any explosive exercises or lift heavy. If you’re doing weights, make sure you do 3 or 4 warm up sets with lighter weights
2. Stretch, Stretch & Stretch
Buy a foam roller, and a lacrosse ball. Use them everyday, and stretch, a lot. Consider taking up yoga or pilates.

3. Do what you enjoy, but modify it a bit
For example, I can’t hit ‘thai pads’ anymore, my shoulders and wrists just can’t take it. So I have to stick to the boxing pads. There’s normally a way to adapt if you are keen enough. Try not to make an excuse and be negative about an injury; you can normally train around them. Be very careful though, if something hurts during or afterwards, its not a sustainable or sensible way to train.
