Five things to remember..
1. We're in the gym to develop various physical qualities (e.g., strength, RFD, power output), and exercises (compound and isolation) are just tools to do so.
Exercise selection will always come down to individual context e.g., goals, capabilities and preferences.
2. You can use both machines and/or free-weights (Haugen et al., 2023; Heidel et al., 2022).
One isn't more 'functional' than the other.
3. Similar increases in muscle size can be elicited across a spectrum of loads and rep ranges, as long as you're working at a close enough proximity to failure (Carvalho et al., 2022; Lopez et al., 2021).
Increases in strength can also be elicited across a range of loading conditions (Schoenfeld et al., 2021), but are greater in magnitude when using heavier external load ( i.e., > 8RM; Carvalho et al., 2022; Lopez et al., 2021).
4. Low frequency (e.g., 2 per week) would mean higher training volume per session, with longer and potentially more fatiguing sessions, but less days where you have to get to the gym.
When equated for volume, higher frequencies allow for relatively shorter sessions and might elicit comparatively lower levels of within-session fatigue. This could allow for more load and/or better quality of work per session, and potentially greater gains. Higher frequencies might also be better from a skill acquisition standpoint.
Ultimately, the best training frequency will be specific to your context and should allow for consistency.
5. While there is a place for slow lifting tempos in certain contexts (e.g., learning a new movement or rehab), slow eccentric and/or concentric tempos are not superior for strength and/or hypertrophy (Azevedo et al., 2022; Behm et al., 2024; Dermott et al., 2022; Enes et al., 2025; Hermes et al., 2023; Wilk et al., 2021).
In fact, the intent to move fast or explosively is suggested to result in relatively greater improvements in strength, RFD and power output.
Recent literature also makes a case for the utilisation of accelerated eccentrics (Handford et al., 2022; Zhang et al., 2025).
But if you want to utilise slow lifting tempos because that's when you feel more in control, go ahead.
