Which is better for a beginner home gym?

The Bowflex SelectTech 840. Its 8 to 40 lb range covers learning presses, rows and swings, while the 97 lb Lifeline is too heavy for most beginners.

The Lifeline. Its single-piece cast iron with a powder coat has no moving parts, while the Bowflex relies on a dial and composite shell that need careful handling.

Is the Bowflex worth it over a fixed bell?

If space is tight and you want several weights, yes. One Bowflex covers 8 to 40 lbs; matching that with fixed bells means six separate kettlebells.

Can the Lifeline replace a set of kettlebells?

No. It is a single 97 lb bell, so it covers heavy swings and rows but not lighter presses, halos or warm-up work.

Which is better for heavy swings?

The Lifeline. At 97 lbs it gives the load most swing progressions need; the Bowflex stops at 40 lbs.

Which has the better handle?

The Lifeline has a wide, thick 1.57 in smooth handle for heavy two-hand work. The Bowflex uses a 28 mm rubber grip that is easier on smaller hands.

Bowflex SelectTech 840 Kettlebell vs Lifeline Kettlebell 44 kg

These are not really competitors. The Bowflex SelectTech 840 is one adjustable kettlebell that covers 8 to 40 lbs in 8 lb steps, so it suits a home gym with limited space and a range of lifts. The Lifeline Kettlebell is a single fixed 97 lb cast-iron bell for heavy swings, rows and presses. Buy the Bowflex for versatility; buy the Lifeline only if you need a heavy fixed bell.
