I’m looking to improve my general all-round fitness really (I want to look amazing).
The way to “look amazing” (for most of us) is to lower our body fat and increase the size of our muscles. There is no such thing as “toning” – that’s just marketing BS.
So you want to lose fat and build muscle? You need a programme, and the required equipment will stem from that.
Start with big compound lifts: Squats, deadlifts, presses, rows to get your major muscle groups working hard and burning fat. There are several off-the-shelf programmes that you can follow: Stronglifts 5×5 and Starting Strength being two of the most popular.
That Joe Wicks guy advocates HIIT sessions in his programme. They require less equipment, and you can choose the ones that you enjoy the most. I alternate punchbag sessions and kettlebell swings, with bodyweight exercises such as squat thrusts. Bear in mind, though, that Joe’s own God-like physique was not built on HIIT sessions – he lifts big.
I do HIIT sessions AFTER my lifting when I go to the gym, otherwise the sessions compromise my ability to lift.
Furthermore, I have found that heavy squatting compromises my cycling. SO I tend to ease off the squats until my major cycling events are over for the year, and then get right back on the squat rack through autumn and winter.
Lots of people say they don’t want to lift heavy weights, because they don’t want to be muscular. All I can say to that is, if you ever find yourself with TOO MUCH lean muscle mass, then that will be a very nice problem to have 🙂
Just be mindful of one thing – to transform your body shape you will need to consistently stress your muscles with weight they have never lifted before. That’s the principle of progression. So ignore the pink plastic dumbbell sets you get in Argos.
So to answer your question: A power rack, an Olympic bar and weights, a pressing bench. Something to do pull ups and dips on. Plus equipment for whatever HIIT sessions you enjoy: kettlebells, punch bag and gloves, whatever.
